Compatibility with the OmniReg® modular pressure regulator make them the industry’s only anti-siphon valves with a pressure regulation option. Additional features include an upgraded bonnet design, a self-cleaning metering system for dirty water applications and a captive plunger solenoid. Plus, the actuator module is removable as a single unit with the diaphragm and internal components held in place, which means no more lost diaphragm screws and springs during installation.\u003c\/div\u003e\r\n\u003c!-- split --\u003e\u003cspan style=\"background-color: initial;\"\u003eKey Features\u003c\/span\u003e\u003cbr\u003e\r\n\u003cul\u003e\r\n\u003cli\u003e\u003cspan style=\"background-color: initial;\"\u003eUpper body and air-vent cap constructed of glass-filled nylon\u003c\/span\u003e\u003c\/li\u003e\r\n\u003cli\u003e\u003cspan style=\"background-color: initial;\"\u003eProvides long-term performance\u003c\/span\u003e\u003c\/li\u003e\r\n\u003cli\u003e\u003cspan style=\"background-color: initial;\"\u003eRugged, double-beaded nylon-reinforced Buna-N diaphragm\u003c\/span\u003e\u003c\/li\u003e\r\n\u003cli\u003e\u003cspan style=\"background-color: initial;\"\u003eEnsures a leak-proof seal\u003c\/span\u003e\u003c\/li\u003e\r\n\u003cli\u003e\u003cspan style=\"background-color: initial;\"\u003eInternal and external bleed (flush mode) \u003c\/span\u003e\u003c\/li\u003e\r\n\u003cli\u003e\u003cspan style=\"background-color: initial;\"\u003eManual operation\u003c\/span\u003e\u003c\/li\u003e\r\n\u003cli\u003e\u003cspan style=\"background-color: initial;\"\u003eAccepts OmniReg modular pressure regulator\u003c\/span\u003e\u003c\/li\u003e\r\n\u003cli\u003e\u003cspan style=\"background-color: initial;\"\u003eEnsures consistent performance\u003c\/span\u003e\u003c\/li\u003e\r\n\u003cli\u003e\u003cspan style=\"background-color: initial;\"\u003eExternally removable self-cleaning metering system\u003c\/span\u003e\u003c\/li\u003e\r\n\u003cli\u003e\u003cspan style=\"background-color: initial;\"\u003eEnsures consistent performance in recycled-water applications\u003cbr\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003cspan style=\"background-color: initial;\"\u003e\u003cspan style=\"background-color: initial;\"\u003e\u003cspan style=\"background-color: initial;\"\u003eOperating \u003c\/span\u003e\u003cspan style=\"background-color: initial;\"\u003eSpecifications\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\r\n\u003cul\u003e\r\n\u003cli\u003e\u003cspan style=\"background-color: initial;\"\u003eFlow range: 1-30 GPM\u003c\/span\u003e\u003c\/li\u003e\r\n\u003cli\u003e\u003cspan style=\"background-color: initial;\"\u003ePressure range: 10-150 psi\u003c\/span\u003e\u003c\/li\u003e\r\n\u003cli\u003e\u003cspan style=\"background-color: initial;\"\u003eOperating temperature: up to 130° F\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003cspan style=\"background-color: initial;\"\u003e\u003cspan style=\"background-color: initial;\"\u003e\u003cspan style=\"background-color: initial;\"\u003e\u003cbr\u003e\u003cspan style=\"background-color: initial;\"\u003e\u003cspan style=\"background-color: initial;\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan style=\"background-color: initial;\"\u003eElectrical \u003c\/span\u003e\u003cspan style=\"background-color: initial;\"\u003eSpecifications\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\r\n\u003cul\u003e\r\n\u003cli\u003e\u003cspan style=\"background-color: initial;\"\u003eSolenoid: 24 V ac\u003c\/span\u003e\u003c\/li\u003e\r\n\u003cli\u003e\u003cspan style=\"background-color: initial;\"\u003eInrush volt-amp: 24 V ac-9.6 VA\u003c\/span\u003e\u003c\/li\u003e\r\n\u003cli\u003e\u003cspan style=\"background-color: initial;\"\u003eInrush current: .4 amp\u003c\/span\u003e\u003c\/li\u003e\r\n\u003cli\u003e\u003cspan style=\"background-color: initial;\"\u003eHolding volt-amp: 24 V ac-4.8 VA\u003c\/span\u003e\u003c\/li\u003e\r\n\u003cli\u003e\u003cspan style=\"background-color: initial;\"\u003eHolding current: .2 amp\u003c\/span\u003e\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003cspan style=\"background-color: initial;\"\u003e\u003cspan style=\"background-color: initial;\"\u003e\u003cspan style=\"background-color: initial;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003cspan style=\"background-color: initial;\"\u003eOptional \u003c\/span\u003e\u003cspan style=\"background-color: initial;\"\u003eAccessories\u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\r\n\u003cul\u003e\r\n\u003cli\u003e\u003cspan style=\"background-color: initial;\"\u003eOmniReg® 5-30 psi regulator (OMR-30)\u003c\/span\u003e\u003c\/li\u003e\r\n\u003cli\u003e\u003cspan style=\"background-color: initial;\"\u003eOmniReg 5-100 psi regulator (OMR-100)\u003c\/span\u003e\u003c\/li\u003e\r\n\u003cli\u003e\u003cspan style=\"background-color: initial;\"\u003eRecycled-water solenoid kit (RW60-KIT);
