PDC In-Line Check Valve From Durabla
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.
