Series CKM Check Valves, normally closed in design, feature a patented diaphragm seal that will neither stick nor chatter and is automatic in action. The valves are not dependent upon gravity so they can be mounted in any position. Even in the absence of reverse flow or pressure, the diaphragm will automatically reposition itself to seal against the valve seat. This is achieved with or without the presence of reverse flow. The unique and patented diaphragm will seal in the identical location every time producing a more reliable and repetitive seal.


  • Self-sealing - are not dependent upon gravity, mounting position or reverse flow, a significant improvement over ball check valves.

  • Silent Operation: No internal sliding or loose parts to slam or vibrate - chattering is eliminated!

  • Dependability: Leak-free sealing protects against the potential hazards created by reverse flow of corrosive liquids such as acids, caustics and chlorine solutions.

  • Repetitive Long Term Sealing: Diaphragm automatically positions itself against seat in the identical location. Superior to ball check valves which often leak at lower pressures.

  • Convenience: Union nut simplifies valve inspection/removal with minimum piping breakdown.

  • Minimal Cracking Pressure: Diaphragm begins to open at approximately 1.0 to 1.5 PSI.

  • Cost Efficient: Designed to improve system performance and competitively priced.
