DFT’s PDC® check valve:
Designed specifically for reciprocating compressors.

The PDC® has 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.

• Pulse-damped design
• Modulating "air" or "gas" applications:
  - discharge of reciprocating air/gas compressors
  - self-sizing
  - accommodates varying flows without chattering
• Mediums:
  - air
  - gas
• Meets API 6D
• ASME B16.10 Face-to-Face dimensions
• One-piece body
• Spring-assisted silent closing
• 2" to 26" Line size available and will quote larger
