Your water savings - Save Lives

  • 100% water tested
  • 150PSI (10,3 BAR) rating
  • Unique “reverse flow” design permits equal pressure distribution on both sides of the diaphragm, regardless of line pressure, providing zero stress to prevent “stretching,” a common cause of valve failure
  • Reverse flow design for water conservation in the event of failure
  • Diaphragm’s self cleaning ports constantly flex, inhibiting sand and silt from blocking valve action
  • Molded shock cone for smooth operation and reduction of water hammer
  • Easy-to-use internal manual bleed lever; bleeds valve downstream; has positive stops for open and closed positions
  • Marine-grade S20P solenoid with stainless steel actuator
  • High-strength glass-filled nylon body and cover with ¼” stainless steel cover bolts and mating brass body inserts
  • Non-rising flow control stem throttles valve from full open to closed position on flow control models
