7000 flow control valves

Bulletin 7000

Flow Control ValvesMICRO-RATIO® Valve assemblies are used

for air, gas and oil proportioning control. The multiplescrew cam assembly provides mechanical adjustmentcapabilities to the air/fuel ratio at each valve positionthroughout the entire capacity range of your burnersystem.

Throttling range is fully adjustable and designed tooperate over the extremely wide turndown capabilitiesof Maxon’s modern burner systems.

Stand-by fuel requirements are simplified byusing tandem-linked “air-gas-oil” valves to providesingle point control for multiple fuel or multiple zonesystems (see photo below).

Flow Control ValvesSeries “Q” Gas Control Valves provide the high

capacity and low pressure drop benefits of a butterflyvalve construction, plus an adjustable gradient featurefor accurate fuel flow control.

They are used independently for throttling of fuelgases and with PREMIX® Blower Mixers andAIRFLO® Mixers for stand-by fuel systems, wherethey allow change-over to alternate fuels without re-adjustment.

Series “Q” Valves are UL (UnderwritersLaboratories) listed for use with air, natural gas andliquefied petroleum gases.

3" Series “Q” Valve

Series “CV” Control Valves incorporate a full-flow, fixed gradient butterfly valve design for highcapacities at low pressure drops, using minimumoperating torque.

This economical assembly includes a minimumstop screw and can be supplied with connecting baseand linkage assembly to mount your electric controloperator.

Versions available with UL (UnderwritersLaboratories) listing for air, natural gas and liquefiedpetroleum gas service.

Series “BV” Balancing Valves are used tobalance gas or air flows in multiple-burner systemsfed by a common manifold. They feature a full-flowbutterfly design with provision for locking in anyposition.

Air Control Valves permit throttling control of air toburners. They feature a fixed gradient butterfly valvedesign with an adjustable minimum stop, frictionbrake screw and provision for manual or automaticoperation. Air control valves are offered in 1-1/2"through 18" pipe sizes.

Design and Application DetailsMICRO-RATIO® Valves

Principle of OperationMICRO-RATIO® Valve assemblies typically consist

of a fixed-gradient air butterfly valve mechanicallylinked to one or more adjustable gradient SYNCHROFuel Control Valve(s).

The tandem linkage gives accurate proportioning ofthe air/fuel(s) ratios required for your specific burnersystem/application.

The multiple screw adjustment feature of theSYNCHRO Valve provides a mechanical means ofadjusting the air/fuel(s) ratios at each of twelve valvepositions throughout the capacity range of each valve.

Maximum application flexibility is provided fromover 500 possible valve combinations.

Air-gas-oil valves in tandem-linked combinationare ideal for multi-zone or stand-by fuel systemcontrol.

Totally enclosed cam assemblies are availableto protect the valve’s internal adjusting mechanismagainst moisture and/or hostile environments.

Air-gas-oil SYNCHRO Valves may be usedindependently for single control or throttling ofmultiple flow paths or fuels.

NomenclatureMICRO-RATIO® Valve assemblies are designated

by listing the individual valves, starting with the airvalve, then each of the fuel valves to be included, aswell as their relative position in the assembly.

Flow Control Valves

Capacities and SpecificationsSYNCHRO and MICRO-RATIO® Valves

GeneralAll Maxon Flow Control Valves are designed forthrottling service only and are not intended fortight shut-off.

Flow direction is not a factor with butterfly-typevalve bodies; however, with poppet-type SYNCHROValves, fluid flow through the valve must only be inthe direction indicated by the arrowhead cast intoeach valve body.

All valve combinations will be assembled in “righthand” flow direction unless specified as “left hand”assembly. When looking directly at the air valveindicator dial, a “right hand” arrangement is indicatedby flow coming from the right side of the fuel valvequadrant and flowing to the left side. A “left hand”assembly is opposite, with flow from left to right.

For instructions for reversing valve body flowdirection in the field, see page 7016.

Torque requirements listed in tables below areimportant and are to be used in selecting yourautomatic control operators. Torque figures (inch-pounds) are additive for your complete MICRO-RATIO® Valve assembly.

Example: For M- 6" x 2" -P MICRO-RATIO® Valve:M- 6" requires 60 in-lbs2" -P requires 90 in-lbsM- 6" x 2" -P assembly requires 150 in-lbs

The automatic control motor you select must becapable of developing at least 150 in-lbs of torque inorder to throttle this particular MICRO-RATIO® Valvecombination if valve is applied at maximum inletpressures shown.

Performance Data

SYNCHRO Oil Valves – #2 Fuel Oil ServiceOil Valves are normally sized for

approximately 5 psi pressure drop. For #2 oilservice, see chart at left.

For preheated #5 or #6 oil, multiply therequired flow rate in gph by the factor given inthe table shown below the chart, then select avalve based upon that equivalent flow of #2 oiland its allowable pressure drop.

For example: To size for 5 psi drop with a 50 gphflow of #6 preheated to 140°F, the multiplier is “2”.Equivalent flow of #2 oil is then 50 x 2, or 100 gph.Chart shows that a 5 psi drop will require use of a1/2" -O -100 SYNCHRO Oil Valve.

Note: The capacities and pressure dropsindicated in this chart are based on flowthrough a wide-open valve. If valve is lessthan fully open, higher drops and lower flowswill result.

Suggested Maintenance/Inspection ProceduresMaxon MICRO-RATIO® Valves

Field Rotation of SYNCHRO Valves inMICRO-RATIO® Valve Assemblies

Flow direction through (-P) and (-O) poppet-typeSYNCHRO Valves must be in the direction indicatedon valve body casting. If reversal of the SYNCHROValve body is required for piping convenience, followthese steps:

1. Loosen neck set screws (one on each side) [1].

2. Remove bracket cap screws [2] and save.

3. Remove valve body [3] while supporting air butterfly[5] and adjusting screw carrier assembly [4].

4. Rotate valve body [3] 180°, then reposition andinstall bracket cap screws [2] loosely.

5. Check carefully that screw carrier assembly [4] islowered into position, then tighten neck set screws[1] into neck indentation.

6. Tighten bracket cap screws [2].

Valve Lubrication Suggestions

Some lubrication of moving parts may berequired. All moving parts, O-rings and cam strips arelubricated at time of manufacturing. A periodicinspection should be performed to insure all partscontinue to move freely and function properly. Aperiodic re-application of lubricant will extend theservice life of your Maxon MICRO-RATIO® Valve.

The following lubricants are suggested:

Manufacturer Lubricant

Keystone Div., #84-EP-2, NLGI #2Philadelphia, PA Lithium base grease

Standard Oil Co. Stanolith grease #42(of Indiana)

Shell Oil Co. Alvania grease #1

Stewart Warner Corp. Alemite lubricant #32

Design and Application DetailsSeries “Q” Adjustable Gradient Gas Control Valves

CB & L assemblies are available for the mostcommonly-used electric and air operators.

Maxon CB & L assemblies are designed toposition control operators, not to support them.User must provide auxiliary support in the form of wallbrackets, floor stands, turnbuckle hangers, etc. tosupport the weight and size of your operator.

Optional tandem linkage assembly is available toconnect two Series “Q” Valves together for control by asingle automatic control operator.

Connecting linkage is available to mount a Series“Q” Valve in a stand-by fuel arrangement withPREMIX® Blower Mixers or Series “66” AIRFLO®

Mixers as shown on page 7018.

The Series “Q” butterfly gas valve is equipped withthe Maxon multiple-screw adjusting cam for adjustingthe flow from maximum to minimum. The numbers onan external indicator strip correspond to a series ofadjusting screws which may be set initially to give thedesired contour to the cam.

A Series “Q” Valve may be used for most gasthrottling applications and provides flexibility ofadjustment.

Series “Q” Valves can be easily adapted forautomatic operation with either electric or pneumaticcontrol operators.

Maxon has designed a broad range of ConnectingBase and Linkage (CB & L) assemblies to properlyposition and align those operators for control of MaxonFlow Control Valves.

Capacities and SpecificationsSeries “Q” Adjustable Gradient Gas Control Valves


All Series “Q” Gas Control Valves are UL (Under-writers Laboratory) listed for air, natural gas andliquefied petroleum gas service.

Torque requirements listed in table at right are tobe used in selecting your automatic control operator.

NomenclatureSeries “Q” Valves are designated first by the pipe

size (inlet and outlet), followed by the letter “Q” toindicate the valve series.Example: 2" -Series “Q” Control Valve

Special application of Series “Q” Valve for stand-by service on PREMIX®

Blower Mixers and Series “66” AIRFLO® MixersPropane is frequently used as a stand-by fuel for

natural gas. When propane is carburetted with air at acentral mixing point and delivered in the regular naturalgas lines at a Btu value and specific gravity permittingperformance characteristics closely matching theprimary fuel, it may be burned in most industrial gasequipment without any change in adjustment.

However, LPG can also often be used in the raw,uncarburetted state. For example, the Maxon Series“Q” Gas Control Valve may be linked to the ratio valveof a Maxon PREMIX® Blower Mixer or Series “66”AIRFLO® Mixer to provide for pre-adjustment of thefuel-air ratio for both the primary fuel and a stand-byfuel.

lessens the chance of internal flow turbulence beingset-up in the piping manifolds and control valve.

– Check fluid flow direction through “-P” and “-O”poppet-type valves. It must flow only in directionmatching the arrow cast into valve body. If neces-sary, valve body may be rotated per instructionsgiven on page 7016.

– Install flow control valves carefully and maintainadequate dimensional clearance to allow fullstroke and travel of the valve’s control linkage.Internal drive mechanisms within a control motormay be damaged if linkage is restricted as to causebinding in high or low flow position.

CAUTION: All Flow Control Valves are designedfor throttling service only and are not intendedfor tight shut-off.

– Main system shut-off should always use amanual “leak-tight” upstream fuel cock.

– Support weight of piping independently. Do notplace any Maxon Flow Control Valve in a pipingbind. Provide pipe hangers and/or special supportfor related manifolds.

– Maxon connecting base and linkage assembliesare designed to locate and/or position thecontrol operator for its interaction with the FlowControl Valve assembly. They are not intended tosupport the weight of the control motor. Specialprovisions will be required to support the weight ofthe control operators.

– Use of pipe heavier than schedule #40 cancause interference with butterfly-type Flow ControlValves and restrict the valve from full opening.

– Flow Control Valves provide the means toadjust fluid and/or gas flows. They should beinstalled with at least four pipe diameter lengths ofstraight pipe before and after the valve. This

Adjusting Instructions

Notice: Only generalized instructions can be providedhere. Detailed adjusting instructions are provided witheach individual Maxon burner and/or mixer system.

General InstructionsImportant: Do not discard packing materialsuntil all loose items are accounted for.

To prevent damage in transit, some connectingbase and linkage components may be packedseparately and shipped loose with your new MaxonFlow Control Valve.

The Flow Control Valve is normally only a part ofyour complete combustion system. Additional pipetrain accessories and control components may berequired for a complete system installation.

Read complete instructions before proceeding,and familiarize yourself with all the system’sequipment components. Verify that your equipmenthas been installed in accordance with the originalmanufacturer’s current instructions.

CAUTION: Initial adjustment and light-off ofburner systems should be undertaken only bytrained and experienced personnel familiar withcombustion systems, with control/safetycircuitry, and with knowledge of the overallinstallation. Instructions provided by thecompany and/or individuals responsible for themanufacture and/or overall installation ofcomplete system incorporating Maxon burnerstake precedence over these provided by Maxon.If Maxon instructions conflict with any codes orregulations, contact Maxon Corporation beforeattempting start-up.

For initial adjustment and/or burner start-up:1. Close all burner fuel valves and cocks. Make

preliminary adjustments to fuel gas regulators.2. Check all electric circuitry. Verify that all

control devices and interlocks are operable andfunctioning within their respective settings/ranges. Be sure all air and fuel manifolds aretight and that test ports are plugged if not beingused.

3. Check that any air handling dampers areproperly positioned and locked into operatingpositions.

4. Disconnect the automatic control motor’slinkage from your control valve’s operating crankarm by loosening the control motor’s connectingrod from the burner’s toggle linkage.

Initial adjustment should only beaccomplished during a “manual” controlmode.

5. Start all system-related fans and blowers.Check for proper motor rotation and impellerdirection. Verify that all control interlocks areworking. Allow air handling equipment to run foradequate purge of your manifolds.

CAUTION: Do not by-pass control panel timerstypically controlling sequential operations.

6. With MICRO-RATIO® Valve combinations ofair and fuel valves, the minimum differentialpressure setting is initially established withthe air valve only.A. By disconnecting the linkage between the air

butterfly valve and interconnected fuelvalve(s), the minimum and maximum limits oftravel on the air valve may be determined.For example, a combustion system may

need the air valve to be 15° open for the“minimum” setting and the “maximum”requirements are satisfied with the air valveopen to 60°. By marking these points on theair valve’s indicating strip, you are ready toreconnect the SYNCHRO Fuel Valve’slinkage to the air valve.

B. The next step involves adjusting theconnecting linkage between the air valveand the fuel valve(s) so that each fuel valvetravels its full quadrant range (i.e. fromminimum to maximum), while the air valveswings from its pre-determined minimum andmaximum positions.

C. With Series “CV” Valves and Series “Q”adjustable-gradient Flow Control Valves,the minimum flow position is set by theirminimum stop screw. This adjustable stop islocated on the side of the screw carrier ofSeries “Q” Valves and at the base of crankarm of Series “CV” Valves. Screwing “in” onthe minimum stop screw produces a physicalstop on the quadrant’s travel that prohibitsvalve from being completely closed off.




5/03


D. SYNCHRO gas and oil valves havemultiple adjusting screws and, when usedalone (without an inter-connected air valve asin the MICRO-RATIO® Valve assemblies), theminimum adjusting screws are not screwedin, thus not permitting flows at the specificminimum flow positions.

E. Series “BV” Balancing Valves have fixedsetting control points. The butterfly-type bodymay be locked in any particular flow positionby simply screwing “in” on the locking Allenscrew on the side of the wheel handle.

CAUTION: Verify all safety interlocks areoperational before opening any main and/orindividual burner valves.

7. Open main and pilot gas cocks, then attemptspark ignition to light pilot while slowly turningpilot gas regulator clockwise and/or adjustableorifice screw counter-clockwise to increase fuelflow. Repeat procedure as necessary until pilotignites, as air might have to bled out of fuelsupply lines before reliable pilot flame isestablished. Pilot gas regulator should normallybe set for as low a pressure as possible.

8. After ignition, adjust pilot flame with pilot gasadjustable orifice for good stable flame shape. A“rule of thumb” is that any pilot over a tennis ballsize is probably too large. This assumes youhave visual access to the pilot flame. If this is notpossible, then adjust pilot to give a strong andstable flame signal through your flame safetycircuit. This signal strength can be read with amicro-amp meter. The signal strength (or range)will be determined by the specific type of flamesafeguard instrument you have with your burnersystem.

9. Re-check pilot ignition by closing pilot gas cockor otherwise causing pilot outage. Re-light andrefine pilot gas adjustment as necessary to getignition within a second or two. The flamesafeguard relays should now power your mainfuel Shut-Off Valve(s).

CAUTION: After completing steps above, re-check all interlocking safety components andcircuitry to prove that they are properlyinstalled, correctly set, and fully operational. Ifin doubt, shut the system down, close pilotcock and contact responsible individual beforeproceeding further.

10. To light and adjust burner on gas:With gas pilot established and flame supervisionsystem operational, opening the main fuel Shut-Off Valve(s) will allow fuel flow to the FlowControl Valve.

11. To adjust SYNCHRO Fuel Control Valve(s):With SYNCHROValve at minimumposition, openupstream fuelcock. Using theAllen wrenchprovided, turnminimum adjustingscrew “down”(clockwise) topermit fuel flow toyour burner.

NOTE: At this point, it is more important to get anykind of flame as soon as possible. The flamegeometry can be adjusted and refined as neededlater.12. Once your flame is established and refined at

this position, and without advancing the screwcarrier quadrant higher, screw all remainingscrews down to at least the same level as yourfirst adjusted screw.

NOTE: A preliminary setting can be established withall the remaining adjusting screws. Generally eachsucceeding screw needs to be screwed inapproximately one full turn deeper than its precedingscrew. A smooth “stair-step” gradient pre-set at thispoint from low to high will simplify the remainingadjustment steps.

CAUTION: If flame is extinguished, immediatelyreturn Flow Control Valve to minimum positionand shut off fuel (if flame safeguard has notalready done so). Turn in slightly on adjustingscrew at point where ignition was lost, thenreturn Flow Control Valve to minimum position,re-establish pilots, open fuel valve and verifyignition.

13. Without advancing the Flow Control Valvequadrant, screw down on #2 screw (one or twoturns). Then slowly advance the Flow ControlValve quadrant to the #2 position. Adjust flameappearance at this new position #2.

NOTE: If firing chamber is of refractory construction,allow your burner system to operate at this low settingfor the necessary dry/cure-out time periodrecommended by the chamber or refractorymanufacturer. Then continue adjustments of FlowControl Valve.

Again, without moving valve, bring #3 and allremaining adjusting screws down to the samelevel as #2 screw. (If approximate pre-setgradient was made earlier, the remaining screwswill already be at or below appropriate levels.)

14. Progressively work your way up through eachadjusting screw position, developing a smoothprogression slope from your first screw to themaximum position.

NOTE: To adjust the flame at any position, you mustmove the Flow Control Valve to the number youdesire to adjust. This aligns the adjusting screwdirectly on top of the fuel valve plunger. A resultingadjustment of the screw is directly applied to the fuelvalve plunger and its interconnected valve bodylinkage.

CAUTION: Oil flames are highly radiant. Use eyeprotection and avoid prolonged viewing. Prepareto shut off oil quickly if there is a noticeabledrop in oil pressure or if ignition does notoccur.

NOTE: To avoid possible damage to cam strips,always turn all higher-numbered screws in as far asthe last one adjusted.

15. Refine adjustment as needed, always turningvalve so that position indicator matches screwbeing adjusted.

For more fuel, turn screw in (clockwise). Forless fuel, turn screw out (counter-clockwise).

If screws must be turned in flush with carriercasting, increase fuel pressure and re-adjust.

16. Repeat procedure for any other fuels.17. Cycle burner from minimum to maximum and

refine adjustment, if necessary. Always setFlow Control Valve to the numbered position youwish to adjust.

For operation with interrupted pilot (asrecommended), shut off pilots and cycle burnerfrom minimum to maximum and back severaltimes to verify the flame is maintained.

18. Reconnect linkage to control motor, plug alltest connections, replace equipment cover capsand tighten linkage screws.

19. Check out overall system operation by cyclingthrough light-off at minimum, interrupting pilot,and allow temperature control system to cycleburner from minimum to maximum and return.

20. Recheck all safety system interlocks for propersetting and operation.

WARNING: Test every UV installation fordangerous spark excitation from ignitors andother possible sources of direct or reflected UVradiation. Use only gas-tight scannerconnections.

21. Before system is placed into full service,instruct operator personnel on proper start-up,operation and shut-down of system. Establishwritten instructions for their future reference.

D. “Push-to-Close” SYNCHRO gas and oilvalves have multiple adjusting screws and,when used alone (without an inter-connectedair valve as in the MICRO-RATIO® Valveassemblies), the minimum adjusting screwsare screwed “in”, thus reducing flows at theminimum flow positions.

WARNING: The “Push-to-Close” SYNCHROValve is adjusted differently than a standardMaxon SYNCHRO Valve. Before installing oroperating, read and comply with all instructionsand warnings shipped by Maxon Corporation inenvelope with your Maxon Flow Control device. Ifyou are unclear about the method of adjustmentor if these instructions were misplaced or notreceived, immediately contact MaxonCorporation in Muncie, Indiana, U.S.A. for a setbefore attempting to use the valve.

CAUTION: Verify all safety interlocks areoperational before opening any main and/orindividual burner valves.

7. Open main and pilot gas cocks, then attemptspark ignition to light pilot while slowly turningpilot gas regulator clockwise and/or adjustableorifice screw counter-clockwise to increase fuelflow.
