Self-sealing, the CMK Series are not dependent on gravity, mounting position or reverse flow, a significant improvement over ball check valves. There is no internal sliding or loose parts to slam or vibrate; chattering is eliminated! The leak-free sealing protects against the potential hazards created by reverse flow of corrosive liquids such as acids, caustics and chlorine solutions. Diaphragm automatically positions itself against seat in the identical location. Superior to ball check valves which often leak at lower pressures.

Union nut on Series CKM simplifies valve inspection/removal with minimum piping breakdown. Diaphragm begins to open at approximately 1.0 to 1.5 PSI.
