100% water tested 150 PSI (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 Engineering grade PVC body and Phillips retaining screws Non-rising flow control stem throttles valve from full open to closed position on flow control models
