INSTALLATION & SERVICE INSTRUCTIONS
Model RCA40DD is a normally closed, pilot operated diaphragm valve with a 1/8" pipe connection for
a remote pilot valve. Inlet and outlet connection is by compression nut and seal. The cover exhaust
port is provided with a 3/8" pipe thread.
This valve is designed exclusively for rapid cycling dust collector service.
The valve has an1 internal bleed, and utilises the system pressure for operation. The only moving
parts are tile diaphragm assemblies and springs. When the remote pilot solenoid valve is energised,
it causes the pilot diaphragm to open, which in turn allows tile main diaphragm to open.
These valves will operate in any position. The cover exhaust port should be shielded against the entry
of rain water, dirt etc.
