SAUNDERSTYPE 'M'BALL VALVES

Method of Operation- Standard handle designedfor operator comfort, 90oaction indicates valveposition.Other Methods ofOperationDiaphagm, piston or electricactuators, fitted withoutremoving the valve frompipeline, cut operation timeand labour.Safety-Stem shoulder/integralwasher restrains stem forincreased safety.Stem Seal-Nitrile rubber or reinforcedPTFE is pressure assisted

and self compensating for100% leaktight performance.Stem-Mild steel stems are treatedto resist corrosion for longworking life. Stainless steeloption gives strength on highpressure applications.Ball-Standard, cast iron, nyloncoated for less frictionalresistance, reduces operatingpower. Stainless steel optionincreases corrosionresistance and meets theneed of 'clean' applicationswith stainless steel body.Bonnet cover-

Prevents ingress of dust anddirt, protects stem fromenvironmental attack.Coating-Special process forphosphate and resin paintcoating ensures all-overcoverage to give all-roundprotection on cast-iron bodiesand easy to clean finish.End Connections-Screwed and flangedconnections suit UK,European and USspecifications to avoidpipeline planning problems.Seats-Pressure assisted, self compen-sating, give complete closurethroughout the pressure range,to stop product waste. Material

Saunders type 'M' full bore valves provide a choice of body, ball, seatmaterials, end connections and methods of operation to satisfy the needs

of the majority of industrial ball valve applications where high flow andcomplete leaktight closure are important. Saunders full bore design is

truly full bore, minimising pressure loss.

These additionalfeatures put type 'M'valves in theforefront of ballvalve design.

1Flow-True full bore design- minimumresistance to reducepump powerconsumption.

2Maintenance-Three piece designallows seat changewithout removingbody from pipelineor breaking valve/pipeline joints.

3Stem/Seal change-Top access designkeeps the valveworking duringstem/ sealmaintenance.

4Installation-Type 'M' valves areavailable forinstallation withoutend connections - tosave space andweight.

5Bonnet Options-A choice ofpadlockingassemblies toprevent expensive(or illegal)interference.

The full type 'M' material range is:-

Grey cast iron body (flanged orscrewed), nylon coated ball, nitrileseats and seal for general applications.

Grey cast iron body (flanged orscrewed) stainless steel ball, Ptfeseats and seal for higher temperatureuse.

Stainless steel body (flanged orscrewed), stainless steel ball, Ptfeseats and seal for 'clean', corrosiveand higher temperature services.

Grey cast iron body (BS1452) (flangedor screwed), cast iron ball, nitrile seatsand seal to suit specific applications,especially sludges.

SAUNDERSSABAL 'MP' BALL VALVES

Three-way valves cut the cost of diverting the flowBased on the design of Sanders rugged straight through ball valves - but withthe addition of a third port - the MP range provides a fast means of divertingline media flow for increased processing safety, flexibility in mixing, batchingand increased production. The three part configuration reduces capital outlay -cutting out the need for treble valve installation. A size range of DN 25 - DN 80is available in both stainless steel and cast iron body materials; two balldesigns in stainless steel are complemented by self compensating Ptfe* seatsand seals.*Ptfe: Polytetrafluoroethylene

Method of operation - leverindicates valve position,reduces manual closureeffort.Other methods of operation- Saunders pneumaticactuators, fitted withoutremoving the valve from thepipeline, reduce your labourcosts.Safety - stem shoulderrestrains stem for increasedsafety, to allow higherpressures - more throughout.

Stem seal - reinforced Ptfe,pressure assisted and selfcompensating for 100%leaktight performance, toincrease production volumes.Stem - stainless steel meetseven higher pressureapplications.Ball - stainless steel, resistscorrosion for long life andmeets the needs of 'clean'applications (with stainlesssteel body) offering the extra

insurance of no productcontamination.Coating - special process forphosphate and resin coatingensures easy to clean finishand all-round protection to cutout costly painting time.End connections - screwedand flanged connections suitUK, European and US specifi-cations to avoid pipelineplanning problems.

Type MRugged, three piece valves available withfemale screwed or flanged endconnections; cast iron/nylon coated orstainless steel ball and seats and seals ofnitrile or Ptfe.The standard method of operation is lever,but pneumatic and electric poweractuators are available for remoteoperation. Type M valves are availablewithout end connections.

MP Bent 'T' PortDesigned for flow switching duties; typeMP valves are supplied with femalescrewed or flanged end connections (sideconnections being removable) in cast ironor stainless steel with Ptfe seats andseals.Two designs of ball (L-port and bentT-port) allow direct transfer of line fluidfrom one pipeline to another or venting

Selection Guide - Ball ValveTypesNotes on SelectionWhilst both the valves shown have 90oaction (MP option of 180o on 'L' port) theyeach have purpose built features andperformance characteristics to meetspecific service needs.Type 'M'This industrial model has the highestcapacity and a full bore streamlined flow.

It can handle liquids, gases, slurries andmany solids with equal ease.

Type MPThe main purpose is in change-overduties, providing safety and economy,from tanks and main line tappings.Designed from Type M service experienceit has identical temperature/ pressurerelationships, but would not be selectedfor 'solids' handling.
