The DFT® Model PDC Silent Check Valve is specially designed for use on the discharge side of reciprocating air or gas compressors. It includes a pulse damping chamber to maintain the disc in the open position during the momentary reductions in flow associated with each cycle of a reciprocating compressor and to protect against premature seat wear.
Features
Pulse damped design
Modulating "air" or "gas" applications:
discharge of reciprocating
air/gas compressors
self sizing - accommodates varying
flows without chattering
