Description
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. The unique poppet will seal in the identical location every time, producing a reliable and repetitive seal.
Features and Benefits:
- 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.
- Minimal Cracking Pressure: Valve begins to open at approximately 1.0 to 1.5 PSI.
- Rugged thermoplastic construction meets highest industry standards.
