n Normally closed design, self-sealing, not dependent upon gravity, mounting position or reverse flow. n Teflon® PFA encapsulated stainless steel spring provides bubble-tight seal mounted in any position. n Rapid closure by spring-loaded poppet helps to eliminate sudden back-flow water hammer. n Positive repetitive sealing: poppet automatically positions itself against seat in the identical location each time for long cycle life dependability. n Minimal Cracking Pressure: Valve begins to open at approximately 1.0 to 1.5 PSI.
