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.

Materials of Construction:  Series CKS Check Valves are available standard in PVC (Polyvinyl Chloride), CPVC, Polypropylene and Kynar® PVDF in sizes 11/2", 2" and 3". Seals are in EPDM, or FKM. Threaded or socket connections are standard.

Features/Benefits:

  • Designed to provide the same superior performance as the existing 1/2", 3/4" and 1" sizes.
  • Rugged thermoplastic construction meets highest industry standards.
  • 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 of 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 poppet 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.
