Anti-Siphon Pressure Vacuum Breakers - 800M4QT

Series 800M4QT antisiphon pressure vacuum breakers include a freeze sensor for use with SentryPlus Alert® technology to monitor temperature nearing the freezing point. The sensor is activated with the BMS/IMS Freeze Sensor Connection Kit to relay a signal to building or irrigation management systems, helping facility personnel take actions that reduce or eliminate PVB replacement and repair. Freeze alerts are distributed according to the BMS/IMS application.

This series is ideal for health hazard continuous pressure applications, such as irrigation systems and industrial process water systems, when exposure to sudden freezing occurs where water enters the equipment at or below its flood rim. Maximum Pressure:150 psi (10.3 bar), Minimum Pressure: 15 psi (55kPa).
