It features a bronze body and a silicone seat. Rated to 150 psi.\u003c\/p\u003e\u003cp\u003eThis 1 inch anti-siphon pressure vacuum breaker backflow preventer helps prevent the reverse flow of polluted water from entering into the potable water supply due to backsiphonage. It consists of bronze body construction, silicone rubber check valve disc, plastic check valve seat, stainless steel springs, a bonnet with silicone rubber O-ring seal, a lightweight plastic disc float, tee handle shutoffs, and test cocks for winterization draining. It is ideal in health hazard continuous pressure applications such as irrigation systems and industrial process water systems where the water enters the equipment at or below its flood rim. The maximum pressure is 150 psi (10.3 bar) and the minimum pressure is 15 psi (55kPa).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eThe silicone rubber sealing float O-ring and seal check disc are resistant to heat, shock, and chemical attack for reliable performance\u003c\/li\u003e\n\u003cli\u003eThe acetal bonnet acts as “freeze plug\" to prevent body damage\u003c\/li\u003e\n\u003cli\u003eThe test cocks are positioned for easy testing and winterization\u003c\/li\u003e\n\u003cli\u003eInternal parts are easy to access and service with no special tools required\u003c\/li\u003e\n\u003cli\u003eInternal parts easily serviceable in line from top of unit\u003c\/li\u003e\n\u003cli\u003eMinimum pressure of 15 psi and maximum pressure of 150 psi\u003c\/li\u003e\n\u003cli\u003eIncludes: Test Cocks\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\u003c\/p\u003e\u003cdl\u003e\n\u003cdt\u003e\u003cstrong\u003eWhat hazard level is this PVB approved for?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eIt is rated for high health hazard (toxic) cross-connections, but only against backsiphonage.
