Replace Those Failing Piston Check Valves-Image

DFT’s PDC check valve-Designed specifically for reciprocating 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
  • Mediums:
    - air
    - gas
  • ASME B16.10 Face-to-Face dimensions
  • One piece body
  • Spring-assisted silent closing
  • 2" to 20" Line size available and will quote larger
  • ASME 150 to 1500
  • WCB, 316 SS & LCC body
  • SS trim
  • SS spring (450°F max)
  • Ends:
    - RF Flanged
    - RTJ
  • Center guided
  • Horizontal or vertical installation
  • Tight shut-off
  • Protected spring
  • Easy maintenance
  • Versatile
  • Options

- Soft seat

- Inconel® X-750 Spring (500 degree F max due to nonmetallic components)

-Monel trim
