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
• Mediums:
  - air
  - gas
• ASME B16.10 Face-to-Face dimensions
• One piece body
• Spring-assisted silent closing
• 2" to 12" Line size
• 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)
