Lead Free* Freeze-Resistant Pressure Vacuum Breakers - LF767FR

Series LF767FR Lead Free* freeze-resistant pressure vacuum breakers are designed to prevent backsiphonage of contaminated water under continuous Pressure into the potable water supply. Its superior design protects the valve body and internal components during sudden freeze conditions. Water inside the PVB freezes from the outside-inward. As the ice forms and expands causing a buildup of pressure, the LF767FR relieves the pressure through a unique relief valve built into the plastic float. Test cocks are positioned at the lowest point of the valve for winterization draining. They feature a bronze body. Maximum working pressure: 150psi (10.3 bar).
