Watts 800M4-FR-SH 1 - Part of the 800M4FR Series
This 1 inch freeze resistant 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, a built-in relief valve to protect the internal components and the body from freezing, tee handle shutoffs, and test cocks for winterization draining. It is ideal in continuous pressure health hazard applications where exposure to sudden freezing conditions such as on irrigation systems and industrial process water systems can occur. The maximum pressure is 150 psi (10.3 bar) and the minimum pressure is 15 psi (55kPa).
Features- Bronze body for durability
- Unique built-in relief valve relieves pressure caused by ice formation
- Female NPT inlet and outlet with quarter turn shutoffs
- Stainless handles
