Waukesha Cherry-Burrell Brand W71/W72RS Sch. 5 Mix Proof Valves Care of Materials

WARNING

Care of Component Materials

NOTE: SPX FLOW recommends the use of an FDA-approved anti-seize compound on all threaded connections.

Failure to comply with the Care of Component Materials could lead to bodily injury.

Stainless Steel Corrosion

Corrosion resistance is greatest when a layer of oxide film is formed on the surface of stainless steel. If film is disturbed or destroyed, stainless steel becomes much less resistant to corrosion and may rust, pit or crack.

Corrosion pitting, rusting and stress cracks may occur due to chemical attack. Use only cleaning chemicals specified by a reputable chemical manufacturer for use with stainless steel. Do not use excessive concentrations, temperatures or exposure times. Avoid contact with highly corrosive acids such as hydrofluoric, hydrochloric or sulfuric. Also avoid prolonged contact with chloride-containing chemicals, especially in presence of acid. If chlorine-based sanitizers are used, such as sodium hypochlorite (bleach), do not exceed concentrations of 150 ppm available chlorine, do not exceed contact time of 20 minutes, and do not exceed temperatures of 104°F (40°C).

Elastomer Seal Replacement Following Passivation

Corrosion discoloration, deposits or pitting may occur under product deposits or under gaskets. Keep surfaces clean, including those under gaskets or in grooves or tight corners. Clean immediately after use. Do not allow equipment to set idle, exposed to air with accumulated foreign material on the surface.

Corrosion pitting may occur when stray electrical currents come in contact with moist stainless steel. Ensure all electrical devices connected to the equipment are correctly grounded.

Passivation chemicals can damage product contact areas of this equipment. Elastomers (rubber components) are most likely to be affected. Always inspect all elastomer seals after passivation is completed. Replace any seals showing signs of chemical attack. Indications may include swelling, cracks, loss of elasticity or any other noticeable changes when compared with new components.

CAUTION

Installation

When installing the valve, ensure that no foreign materials (e.g. tools, screws, welding wire, lubricants, cloths, etc.) are enclosed in the system.

Location

Isolate products away from the valve prior to performing maintenance.

Welding Instructions

Before attempting to buttweld an automatic valve into a line, disassemble the body from the actuator. Dissipate heat away from the valve body to prevent warping.

The valve must be in a vertical position to ensure that the vent/ drain outlet system functions properly.

The vent/drain outlet at the bottom of the Mix Proof valve must no

t be obstructed. The unrestricted vent/drain outlet must allow leakages and cleaning/rinsing/sterilization fluids to go to atmosphere in order to guarantee mix proof safe separation. If hoses, pipes, or other components are mounted to the vent/drain outlet to prevent splashing of leakage and cleaning/rinsing/ sterilization fluids, then they must be designed such that the fluids flow freely to atmosphere.

Locate the valve for easy access for inspection.

Ensure that the valves and pipe systems dr piece body option enables the positions of the connections to be adjusted in relation to each other.

Prior to installing, thoroughly inspect each valve. When using buttweld two-piece body valves, clamp connections must be used on either the upper or lower body to allow for servicing of the oring seal between the bodies. This does not apply to single-piece bodies.

Fittings

Pipeline Support

When using suitable fittings, Mix Proof valves with detachable connections can be installed in a pipe system per the fitting requirements. The valve must be installed free of tension. After the valve is installed in the pipe system, attach the control air hoses and connect the electrical supply.

Install adequate supports to prevent strain on the fittings, valves and equipment connections.

1. Install supports at least every 10 feet on straight runs of piping. (Figure 2, item C).

2. Install supports on both sides of the valves as close as

ssible to the connections. (Figure 2, item D).

3. Install supports at each change of pipeline direction. (Figure 2, item E an

4. For pipelines passing through walls, floors or ceilings, provide

least 1 inch (25 mm) of clearance around the pipe to allow

at for expansion and contraction. (Figure 2, item G).

In higher temperature applications, ensure proper accommodation for thermal expansion in the stresses on the valve bodies. Excessive mechanical and thermal stresses can distort and damage the valve bodies.

Operating Parameters

Temperature Range:

No special precautions are required for applications within a temperature range of 32°F to 180°F (0°C to 82°C).

For applications above 190°F (88°C)

, clearances can be affected by excessive thermal expansion when the valve is installed in compact fabrications or manifolds. Valve bodies have thicker cross-sections than tubing, but thermal expansion can affect clearances in interconnecting piping sections.

Operating valves above 180°F (82°C) could result in shortened life of elastome

rs and/or erratic valve operation.

If operating below 32°F (0°C):

• Control air must have an appropriately low dew point.

• Valve stems must be protected from icing to ensure long

ing life for valve stem seals.

Maintenance

Maintenance Intervals

Maintain adequate stock of replacement parts. See the items in bold beginning on page

Maintenance intervals should be determined by the user and specific application, based on the following conditions:

• Daily operation period

• Sensoring frequency

• Application parameters, such as temperature, pressure, and flow

• Product type

• CIP time and temperature

Use the following recommendation as a rough guide:

• For fluid temperatures ranging from 180°F to 212°F (82°C to 100

°C): approx. every 3 to 6 months

• For fluid temperatures of 140°F (60°C) and lower: approx. every 12 months

The values listed above are only general guidelines and do not apply, for example, to fluids which crystallize on contact with air. The values listed are subject to the chemical resistance of the seal material.

38 for recommended spare parts.

W70 Series Mix Proof valves operate best at temperatures below 180

°F (82°C), regardless of seal type.

The maximum temperature of 280°F (138°C) listed for the seat seal type is the rating for the elastomers only, in a static condition. This is not the temperature rating for the valve in operation.

The 180°F (82°C) max. rating also applies to valves welded together in a manifold. Operating W70 Series Mix Proof valves at temperatures above 180 elastomers and/or erratic valve operation.

DANGER

VA100-359b

CAUTION

Inspection

Do not put a hand into the yoke or body of a pneumatically-actuated valve.

Lubrication

Inspect the following on a regular basis:

• Actuator connections for air leaks

• Valve body and stem O-rings

• Valve seats (If leakage occurs, see “Troubleshooting” on

page

61.)

• Pneumatic connections:

– Air pressure at supply connection

– Air lines for kinks and leaks

– Threaded connections for tight fit

– Clean air filter at regular intervals

• Electrical connections secure on control module:

– Wire connections tight on terminal strip

– Electrical connections to control module

– Threaded strain relief for tight fit.

No lubrication is required other than as noted in the disassembly and assembly procedures. Use Dow Corning #7 or equivalent food grade non-petroleum (silicone) grease on seals and O-rings.

Cleaning

Avoid splashing any liquid into the air vent of the actuator during clean up

NOTE: Actuate each valve or use seat lifting to ensure effective cleaning and sanitizing. Expose all product-contact surfaces to the appropriate cleaning solutions.

Apply Bostik Never-Seez® White Food Grade with PTFE or equivalent to all bolts and threaded stem parts.

Cleaning-In-Place (CIP)

CIP methods can be used to clean installed automatic valves without disassembly. Select methods based on the specific requirements of sanitarians and each application. Check with local chemical suppliers for the most effective cleaning agents and procedures intended for the application, in order to properly dissolve the product residue. Ensure that the cleaning agent is compliant with the temperature range and elastomer material.

Mix Proof valves can be fitted with a 1/4 NPT flush connection for rinsing the area between the seats and the vent/drain port. The area can be flushed regularly in the event of long times between CIP cleanings. See “External Flush - Liquid Vent Cavity” on page

10.

08/2018 95-03091 Page 23

Maintenance Waukesha Cherry-Burrell Brand W71/W72RS Sch. 5 Mix Proof Valves

CAUTION

Cleaning Procedure

Mix Proof valves are designed to use a cleaning solution supplied by a CIP system. The vent outlet/cavity must be unobstructed to guarantee the leakage of fluid to atmosphere.

During valve opening and CIP cleaning, fluid escapes from the drain port. Drain it off to prevent any possible hazard to personnel.

Establish cleaning procedures for each installation depending on product characteristics, operating parameters (temperature, velocity, valve cycles), and product velocities.

The following statements are intended as suggestions or guidelines for cleaning procedures and will vary by application:

• For seat lifting valves, when the upper or lower body is in CIP, seat movement should occur. Seat cleaning positions are factory-set and marked in the yoke area. Seat cleaning will produce visible leakage from the vent outlet. Brief multiple lifts should occur for each step in the CIP program, excluding the initial rinse.

NOTE: Seat cleaning is not recommended during the initial rinse.

• Maximum Solution Temperature is 180°F (82°C).

• Maximum line pressure during seat cleaning is 90 psi (6.2 bar).

• Minimum cleaning solution velocity is 5 ft/s (0.3 m/s).

• Cleaning time is dependent on the inlet pressure. The recommended cycle time is 3 to 5 seconds per cycle after the valve achieves the seat clean position. This seat clean cycle time of each valve should be visually confirmed during commissioning.

• Typical cleaning procedures include pulsing the seat during cleaning until the valve has been demonstrated to be clean. This is usually accomplished in 3 to 5 consecutive pulses per step in the CIP program; however, each installation and product varies, so pulsing should continue until all product/ debris is removed.

• For the optional external flush of the vent cavity, water flush can be activated during the final rinse.

• Every few months of operation, remove and inspect one valve in the system to ensure that complete cleaning is being achieved.

Actuator O-ring and Bearing Replacement

The valve stems and actuator must be removed from the valve body before servicing the actuator components.

Although WCB fully-maintainable actuators are designed with a contained spring for safety, always use caution when handling any piston/spring assembly as any compressed coil spring can be extremely dangerous.

NOTE: Do not pressurize the actuator with air when the stems are removed. This may tear the O-rings and cause the actuator to leak air when it is re-assembled.
