Care of Stainless SteelWaukesha Cherry-Burrell Brand W60/W80 Valves
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).
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
Page 895-0302208/2018
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.

General InformationInformation in this manual should be read by all personnel
involved in installation, setup, operation and maintenance of
W60/W80 valves.
Always use installation tools and lubricants recommended by
SPX FLOW. Waukesha Cherry-Burrell brand products are
subject to intensive intermediate and final leakage and functional
tests.
W60/W80 Series valves meet 3-A and EHEDG standards for
sanitation, design and style.
Factory InspectionEach Waukesha Cherry-Burrell brand valve is shipped
completely assembled, lubricated and ready for use.

Equipment Serial NumberWaukesha Cherry-Burrell brand valves are identified by a serial
number found on the label on the actuator cylinder.
The recommended operating temperature is determined by the
material used for the seals.
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.
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
working life for valve stem seals.
Solenoid valves may not be used in the control module in room
environments below 32°F (0°C) and over 140°F (60°C), as function cannot be guaranteed.

*Operating conditions such as flow rate and pressure must be considered when operating near maximum
temperature rating.
To avoid electrocution, ALL electrical
work should be done by a registered
electrician, following industrial safety
standards and local codes. All power
must be OFF and Locked Out during
installation.
When installing valves, ensure that no foreign materials (e.g.
tools, screws, welding wire, lubricants, cloths, etc.) are enclosed
in the system.
Welding Instructions
Inspect each valve prior to installation.
When using buttweld connections on
two- and three-piece body valves, clamp
connections MUST be used on one or
more bodies to allow service to the body
o-ring(s) after installation.
W60/W80 valves with welded connections require the following
before welding:
1. Remove the stem and actuator assembly. See “Valve
Removal” on page 19.
2. Remove all seals from the body.
3. Weld the body into position, ensuring that the connection is
free of tension and distortion.
4. Dissipate heat away from the valve body to prevent warping.
Air SupplyInstall the valves using dry, filtered air. Lubrication is not required.
If using lubricated air, refer to the solenoid manufacturer’s specifications.
Pipeline Support

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.
1. Remove the cap screws (Figure 44, item 9) and pull the yoke
(item 12) from the actuator cylinder (item 4).
2. Pull the lower stem (Figure 45, item 3) to remove the caged
spring assembly from the actuator cylinder.
3. Using a 5/8-inch wrench on the lower stem (Figure 46, item
3) and a 3/8-inch wrench on the upper stem (item 2), unscrew
and remove the two actuator stem halves.
4. Turn the piston/spring assembly (item 10) over.
5. Install the actuator stem halves in the piston/spring assembly.
See Figure 46 for Air-to-Raise configuration; Figure 47 for
Air-to-Lower configuration.
Clean, prime and apply Loctite® 2440 Thread Locker, according to manufacturer’s specifications, to the upper (items 1,
1a) and lower (item 3) stems (See Figure 36 and Figure 37
on page 40). Torque the stems to 200 in/lbs for 4" and 5"
actuators; 400 in/lbs for 6" actuators.

Silicone Lubricant or equivalent.
7. Install the piston/spring assembly in the actuator cylinder and
assemble them with cap screws (Figure 48, item 9).
8. Reverse the vent plug (Figure 48, item 13) as follows:
Air-to-Raise Actuator: The vent plug must be located on TOP
of the actuator in Port B (Figure 48, item B).
Air-to-Lower Actuator: The vent plug must be located on the
SIDE of the yoke in Port A (Figure 48, item A).
