Installation

CAUTION: 

When installing the valve, ensure that no foreign materials 

(e.g. tools, screws, welding wire, lubricants, cloths, etc.) are enclosed in 

the system.

Location

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

Ensure that the valves and pipe systems drain properly. The two-piece body 
option enables the positions of the connections to be adjusted in relation to each 
other.

CAUTION: 

Milk and milk products must be isolated away from the valve 

prior to maintenance.

Welding Instructions

Prior to installing, thoroughly inspect each valve. When using buttweld two-
piece body valves, use clamp connections on either the upper or lower body to 
allow the o-ring seal between the bodies to be serviced.

Mix Proof valves with welded connections require the following to be performed 
before installation:

CAUTION: 

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.

•

Prior to installation, remove the stem actuator assembly and lower bearing 

carrier.

•

Remove all seals from the body.

•

Weld the body into position, ensuring that the connection is free of tension 

and distortion.

CAUTION: 

Welding must be performed by qualified personnel.

Air Supply

Install the valves using dry, filtered air. Lubrication is not required. If using 
lubricated air, refer to the solenoid manufacturer’s specifications.

Flow Direction

The valves should be installed to close against the flow to prevent hammering.

Fittings

When using suitable fittings, Mix Proof valves with detachable connections can 
be installed in the 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 it to the electrical supply. 

Contact WCB at 1-800-252-5200 for more information on our wide variety of 
fittings for all applications.
