Installation & Operation
Valve should be installed with reasonable accessibility for service
whenever possible - repair service kits are available. Keep pipe
or tubing lengths to a minimum with inside clean and free of
dirt and chips. Pipe joint compound should be used sparingly
and applied only to the male pipe - never into the female port.
Do not use PTFE tape to seal pipe joints - pieces have a
tendency to break off and lodge inside the unit, possibly causing
malfunction.
Valves will operate when mounted in any position. They are
also suitable for vacuum service. A pilot pressure of 207 kPa
(30 psig) or more is recommended to operate these valves.
Pilot pressure does not need to be increased as line pressure
is increased.
Series C & CW (wall mounting) valves can be operated either
normally closed to pressure or normally open to pressure.
Connect inlet to port “A” for normally closed valve. Port “B” is
exhaust. Connect inlet to port “B” for normally open valve. Port
“A” is exhaust. Plug exhaust port for 2-Way operation.
Factory Pre-Lubrication - All valves are pre-lubricated at
assembly with a petroleum based grease. Filtered and lubricated
air is necessar y for maximum valve life and minimum
maintenance.
Service Procedure
!
Caution: Shut off air supply and exhaust pressure trapped
within the unit before servicing.
Servicing Valve & Actuator Assemblies:
To remove the
pressure actuator assembly (item 11) from the
valve body, unscrew the mounting screws (item 15). Remove
the piston and lip seal from the piston cap (item 14). To remove
the spool, spool guide, and seals from the valve body, unscrew
the end plug using a 3/8" Allen wrench. Then gently press on
the “pin” side of the spool until it slides out of the valve body.
