Air/Solenoid Valve Port Connections: W70 Series Mixproof Valves
Clippard Solenoid Configuration
• DC only
• 3-way action
• Mix Proof valves
• Air boost requires (2) solenoid. Ports on base line up
with lettered solenoid locations
Exceptions
1. W60/W80 and W68/W88 Series 3-Position, Air-to-
Raise Valves uses two Clippard Solenoids (see page)
2. Mix Proof Non Seat Lift uses AC Parker Solenoid
All functions of W-70 mix proof valves are pneumatically
controlled using a 72 to 100 psi (4.9 to 6.9 bar) clean air
supply.
Up to three air supplies controlled by solenoid valves
supply air to valve actuator (Figure 6). For non seat lift
valves, ports A and C are not provided on the actuator.
ON = Solenoid energized (OPEN).
OFF = Solenoid de-energized (CLOSED).
Solenoids are normally closed (N.C).
Air connections are 1/8 NPT
