CARE OF STAINLESS STEEL _____________________________________________________________ The stainless steel components in Dixon Sanitary equipment are machined, welded and assembled by skilled craftsmen using manufacturing methods that preserve the corrosion-resistant quality of the stainless steel. Retention of corrosion-resistant qualities under processing conditions requires regular attention to the precautions listed below.

1. Regularly check all electrical devices connected to the equipment for stray currents caused by-improper grounding, damaged insulation or other defects. Corrosion: "Pitting" often occurs when stray currents come in contact with moist stainless steel.

2. Never leave rubber mats, fittings, wrenches, etc. in contact with stainless steel. Corrosion: Pitting

or galvanic action. Objects retard complete drying, preventing air from reforming the protective oxide film. Galvanic corrosion occurs when two dissimilar metals touch when wet

3. Immediately rinse equipment after use with warm water until the rinse water is clear. Clean the

equipment (manual or CIP) as soon as possible after rinsing. Corrosion: discoloration, deposits, pitting. Product deposits often cause pitting beneath the particles.

4. Use only recommended cleaning compounds. Purchase chemicals from reputable and responsible

chemical manufacturers familiar with stainless steel processing equipment They continuously check the effects of their products on stainless steel.

5. Use cleaning chemicals exactly as specified by the manufacturer. Do not use excessive

concentrations, temperatures or exposure times. Corrosion: Pitting, discoloration, stress cracks. Permanent damage often occurs from excessive chemical concentrations, temperatures, or exposure times.

6. For manual cleaning, use only soft non-metallic brushes, sponges, or pads. Brush with the grain

on polished surfaces, avoid scratching the surface. Corrosion: Pitting, scratches. Metal brushes or sponges will scratch the surface and promote corrosion over a period of time. Metal particles allowed to remain on a stainless steel surface will cause pitting.

7. Use chemical bactericides exactly as prescribed by the chemical manufacturer in concurrence with

local health authority. Use the lowest permissible concentration, temperature, and exposure time possible. Flush immediately after bacterial treatment. In no case should the solution be in contact with stainless steel more then 20 minutes. Corrosion: Protective film destroyed. Chlorine and other halogen bactericides can destroy the protective film. A few degrees increase in temperature greatly increases chemical activity, and accelerates corrosion.

8. Regularly inspect the joints in pipelines. Be sure all connections are tight fitting without binding.

Corrosion: Crevice corrosion. Small crevices caused by improperly seated gaskets will promote crevice corrosion. Stainless steel under stress will develop stress cracking especially in the presence of bactericides containing chlorine.

9. Regularly inspect equipment for surface corrosion (i.e. pitting deposits, stress cracks, etc.). If

deposit or color corrosion is detected, remove it immediately using mild scouring powder and detergents. Rinse thoroughly and allow to air dry. Review production and cleaning procedures to determine the cause. Note: If corrosion is not removed, the protective film cannot be restored and corrosion will continue at an accelerated rate.


2- WAY BALL VALVE MANUAL OR AUTOMATIC

Application Dixon Sanitary's BV2 Series ball valves are specially designed to 3A standards and meet rigid specifications of Food Processing Industries. The cavity filled design will insure product integrity and simplify maintenance in critical process applications. There are no cavities or dead space in the flow path, consequently, no settling areas where contamination could develop. The BV2 is also available with non-encapsulated seats for applications not requiring cavity fillers. The superior craftsmanship, choice materials, top quality strength and surface finish make the BV2 the preference of many wineries, breweries, and a multitude of other industries with sanitary, recirculation, mixing, and blending requirements. Various end types, and accessories make this a highly versatile valve. Working Principle The BV2 is controlled remotely by an actuator, or operated manually with a handle*. The actuator is available in a pneumatic or electric design. Bradford pneumatic actuators are available in spring return or double-acting. Electric actuators are available in a variety of voltages and options. Please see the Bradford “Complete Valve Automation” catalog. A comprehensive range of switch units, solenoid valves, and positioners are available for varying degrees of control.

Features and Benefits

• Rated at 1,000 psi WOG (water, oil and gas) • Balanced encapsulated construction minimizes cold

flow. • Live loaded stem packing. • Precision stainless steel balls reduce torque, and friction

losses while extending seat life. • Conforms to 3A Sanitary Standard 68-00. • Fully encapsulated construction produces bubble tight

seal. • Operating parts are stainless steel type CF8M (316)

conforming to ASTM A351, solution annealed and passivated for corrosion resistance

• Integral ISO 5211 mounting pad • I/D polish is RA 12 minimum • Lockable handle can prevent accidental actuation when

used. • Standard internal entry blow out proof stem design. • Full port design matches ball and seat ports to tube ID

for lower pressure drop and less turbulent flow. • Compact design for areas with tight space restrictions. • No-encapsulated seats available.
*An actuator is recommended for valves 3” and larger. Consult Bradford.

BradfordINSTALLATION PROCEDURES

Prior to installation:

• Remove the valve from shipping container and inspect for damage. o CAUTION: Do not attempt to install a damaged valve. o NOTE: Retain the original packaging in the event a return is necessary.

• The ball valves and the mating surfaces should be inspected to assure gasket surfaces are free of defects.

• Valves should not be installed between ferrules with damaged faces. • Tubing should also be checked for proper alignment. • Ball valves should never be used to align improperly positioned tube. • The distance between ferrules should be checked to assure proper clearance of

valve installation. Valve Installation:

• For convenience in packaging and storage, some valves are shipped partially assembled including body assembly and handle assembly. (Refer to assembly and disassembly instructions.)

• The valve should be cycled to assure no binding or interference is taking place. • Install adequate line supports to prevent strain and stress on fittings, valves, and

connections. o Support straight runs of tubing at least every ten feet. o Install supports on both sides of valves as close to the connection as

possible. o Install supports at each change of line direction. o For lines penetrating walls or floors, allow a minimum of 1” clearance for

expansion and contraction. • Align valves and gaskets such that they are centered with the ferrules faces.

Clamp ends must be parallel in all planes and on centerline. o CAUTION: Failure to insure line ends are parallel and centered could

prevent proper sealing. Improperly sealed valves will leak. • Tighten all standard clamp connections to 25 in-lbs and high pressure bolted

clamps to 20 ft-lbs. • After placement in the line, test the operation of the valve.

Valve installation for other end connection types:

• Follow the same guidelines as described above. o CAUTION: Do not attempt to butt-weld a valve into a line without first

removing the actuator and valve body subassembly. Dissipate heat away from the valve body when welding.

BradfordMAINTENANCE INSTRUCTIONS

Bradford Ball Valves are designed and manufactured to be a long life valve under normal circumstances and do not require any routine maintenance or lubrication. It is recommended that the following practices be followed on at least a monthly basis.

1. Cycle the valve from full open to close to assure operability. 2. Check fasteners for evidence of loosening. 3. Inspect valve and surrounding area for previous or existing leakage at the flange

face, body, or stem area. 4. Check pipe or wiring to actuator for loosening, corrosion or defects and make

corrections as required.

However, if maintenance is required, due to unusual wear or service conditions the following procedures should be followed:

REMOVAL FROM THE LINE

Prior to loosening the ferrule clamp bolts (with valve in the open position):

• WARNING: To prevent personal injury: o Depressurize the piping at the valve. o Drain tubing run as much as possible. o Cycle the valve to drain any trapped fluid from the body cavity. The valve

should be left fully open or fully closed. o Vent line to relieve any pressure.

Close valve, then: • WARNING: To prevent personal injury:

o Disconnect all air and electrical power from the actuator, solenoid valve, and switch box, (if applicable) and tag for reinstallation.

o Remove the actuator, solenoid valve, and switch box, if any. o Loosen clamps to decompress valve gasket seals. o Secure necessary lifting equipment to valve assembly if necessary o Remove clamps and valve from between ferrule.

BradfordDISASSEMBLY – ASSEMBLY PROCEDURES

1. For valves with Clamp end connections:

2. Loosen and remove the clamps connecting the valve to the piping. Then, remove

the valve and gaskets.

3. Loosen and remove the hex nuts and lock washers from the bolts.

4. Pull the end caps free from the body.

5. For valves with welded end connections:

6. The valve can be disassembled with the body subassembly swung out from the end fittings or it can be disassembled with the body subassembly completely removed from the end fittings.

7. To swing out the body subassembly from the end fittings: i. Open the valve. ii. Loosen the hex nuts. iii. Remove the bolts, nuts, and lock washers between the body. Do not

remove the bolt that holds the ring on the body. iv. Spring the connecting piping 1/8" to remove the compression on the

body from the end caps. v. Swing the body out from the end fittings until the body completely

clears the end caps. The body’s swing out ring will rotate about the bolt.

vi. The sprung piping can now be returned to its original compression, if desired.

8. To remove the entire body subassembly from the piping, in step iii above, remove

all bolts.

9. Pull the end caps free from the body. Remove the body seals and encapsulated ball seat.

10. Turn the stem to close the ball. Then, slide the ball out of the body, taking care

not to nick or scratch the ball.

11. Loosen and remove the handle bolt and cap from the stem. Remove the handle, lock plate, and washer.

12. Unscrew and remove the gland nut and spring washer.

13. Push the stem into the body and out an open end of the body. Remove stem o-ring and thrust washer.

14. Remove the gland ring and PTFE stem packing rings.

15. Remove the stopper from the body.

16. Before reassembling the valve, examine the parts and repair or replace damaged

or worn parts. Bradford recommends using new seats and seals at each assembly.

17. Insert the stem (with o-ring) and PTFE thrust washer into the body bore and through the stem bore in the body.

18. Install PTFE stem packing rings over the stem and into the body bore.

19. Install the gland ring and spring washer such that its concave side is facing

upward.

20. Lubricate the gland threads with appropriate lubricant. Install and tighten the gland to compress the packing. The gland should be tightened just until snug. (Over-tightening significantly raises stem torque.)

21. Lubricate the stem threads with an anti-galling lubricant.

22. Install the PTFE washer over the stem. Place the handle on the stem such that the

handle is parallel to the line when the valve is in the open position.

23. Install the handle washer and the handle nut.

24. Position the stem to close the valve. Insert the ball into the body. Slide the stem tang into the ball slot, being careful not to nick or scratch the ball.

25. Rotate the stem until the ball is in the open position.

26. Install valve seat into the body.

27. Place a new body seal in the mating cavities in the end caps making sure the seats

and seals remain in position.

28. For valves with Clamp end caps, insert the end caps onto the body, taking care not to cut seals.

29. For valves with end caps welded into piping, with valve open, spring end caps

outward and slide body between them. Release spring force from end caps to allow ends of end caps to enter body. Take care not to cut seals.

30. Turn the stem and close the valve.

31. Install bolts with washers. Install and hand-tighten nuts.

32. Wrench tighten nuts in sequence shown in Table 1, keeping gap between body

and end caps even and until valve stem breakaway torque is reached. The torque is measured stem torque as valve leaves closed position. Measure stem breakaway torque for several cycles to verify repeatability.

33. If the valve has Clamp end caps, reinstall the valve into the piping using

appropriate gaskets and clamps.

34. If practical, leak test the seats, gaskets, and packing. Notes: Bradford recommends replacement of any valve exposed to fire.

TABLE 1: TIGHTENING PROCEDURE FOR END CONNECTIONS 1. Hand-tighten fasteners. 2. Wrench-tighten each fastener in the sequence illustrated until lock washers begin to compress. 3. Continue tightening bolts 1/8 turn until recommended assembly torque value (Table 2) is achieved. 4. Confirm valve torque at stem.

CLEANING Clean metal parts, as necessary, using solvent compatible with process fluid and a non-abrasive cloth. COP of valve is done as stated in B4.1 of the 3A Standard for Ball-Type Valves for Milk and Milk Products, Number 68-00. Component Inspection:

• Inspect all valve components for wear or damage. o Replace valve seats if cracked, worn, or deformed. o Replace stem bushings if cracked or worn. o Replace ball if damaged or worn. o Replace any fasteners that have stripped or damaged threads.

• If extra valve seats are stored for longer than 2 weeks: o Store in a cool dry environment (75˚F). o Do not expose to direct sunlight. o Protect from contamination, such as dust or other foreign particles.

Certification of Compliance Description: COP for Encapsulated Ball Valves Bradford certifies its encapsulated ball valves comply with the following definition of manual cleaning as found in 3-A® Sanitary Standards for Ball Type Valves, Number 68-00: “B4.1 Manual Cleaning (COP): Shall mean soil removal when the equipment is partially or totally dissassembled. Soil removal is effectedwith chemical solutions and water rinses with the assistance of one or a combination of brushes, nonmetallic scouring pads and scrapers, high or low pressure hoses and tank(s) which may be fitted withrecirculating pump(s), and with all cleaning aids manipulated by hand.
