Series CKM Self-Closing Thermoplastic Check Valves...

Series CKM Self-Closing Thermoplastic Check Valves...
Patented Diaphragm Design Assures Dependable, Repetitive, Bubble-Tight Sealing... and They Can Be Mounted in Any Position!

Features/Benefits:

Patented Design: Self-sealing - they are not dependent on 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 on Series CKM 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.
Great Selection: Molded valves available in Geon ® PVC, Kynar ® PVDF, glass-filled Polypropylene, and now Corzan ® CPVC. Series CK available in PTFE.

CKM(series) 050(size) V(seal material) - PV(body material) Part numbers shown are Viton seals with PVC bodies. • For EPDM seals, change "V" to "EP" (CKM050EP-PV) • For Kynar PVDF body, change "-PV" to "-PF" (CKM050V-PF) • For Polypropylene body, change "-PV" to "-PP" (CKM050V-PP) • For Corzan CPVC body, change "-PV" to "-CP" (CKM050V-CP) Standard connections are threaded. For socket connection, add "S" after seal material (CKM050VS-PV) For spigot or other connection types, consult factory.
