• 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
