Watts 3/4 in. FPT in. X 3/4 in. FPT in. Bronze Vacuum Breaker

Description

This 3/4 inch lead-free anti-siphon pressure vacuum breaker backflow preventer valve model 765EBV-FZ prevents the reverse flow of polluted water from entering into the potable water supply due to back siphonage. It consists of a 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 shutoff, 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 (55 kPa). The pressure vacuum breaker includes a freeze sensor for use with SentryPlus Alert(R) technology to signal when ambient temperature approaches the freeze threshold. Activated through an add-on connection kit, the sensor also triggers freeze alerts to facility personnel. Connection kit available for BMS/IMS Building/Irrigation Management Systems.
