Design:
Series CKS Check Valves are normally-closed in design. They feature a corrosion resistant PFA encapsulated spring which energizes a poppet seal that will neither stick nor chatter and is automatic in action. The valves are not dependent upon gravity or reverse flow and represent a significant improvement over ball check valves. They can be mounted in any position. Even in the absence of reverse flow or pressure, the poppet will automatically reposition itself to seal against the valve seat.

Operation:
Flow entering the valve inlet will open the valve by pushing the poppet off the valve seat. In this position, the valve seat is kept clean by flushing action of the internal flow, keeping the entire sealing area free of particles which could cause leakage. If the inlet flow is stopped, or backflow of a higher pressure is sensed, the spring-loaded poppet will automatically reposition itself, closing off the valve seat. Reverse flow or pressure is not required to close the valve when the inlet stops.

Features

  • Designed to provide the same superior performance as the patented Plast-O-Matic diaphragm check valve.
  • Normally-closed design, self-sealing, not dependent upon gravity, mounting position or reverse flow, a significant improvement over ball check valves.
  • Leak-free sealing protects against the potential hazards created by reverse flow corrosive liquids such as acids, caustics and chlorine solutions.
  • PFA encapsulated stainless steel spring provides bubble-tight seal mounted in any position.
  • Rapid closure by spring-loaded support helps to eliminate sudden back-flow water hammer.
  • Positive repetitive sealing: poppet automatically positions itself against seat in the identical location each time for long cycle life dependability.
  • Convenience: In 1.5"" and 2"" sizes, union nuts simplify valve installation, inspection and removal.
  • Minimal Cracking Pressure: Valve begins to open and approximately 1.0 to 1.5 PSI.
  • Available in PVC, Kynar® PVDF, Polypropylene, and now CPVC. Socket connection available instead of NPT threads. EPDM seals available instead of Viton.
