This lead free automatically reseating temperature and pressure relief valve has a 1 inch NPTF female inlet, 1 inch NPTF female outlet, 3 inch coated thermostat, pressure relief setpoint of 150 psi, and temperature relief setpoint of 210 degrees F. This valve can be installed directly in tank tappings for commercial applications to provide protection for hot water supply tanks and hot water heaters. It features a lead free copper silicon alloy body, tamper resistant bonnet screws, and test lever. Includes a nonrestrictive discharge drain line flood sensor with SentryPlus Alert(R) technology to detect excessive water discharges from the relief valve. When paired with an add on connection kit, the sensor is activated to relay alerts for potential flooding events. Connection kit options include BMS, cellular communication, and the Sensor Control Monitor which enables integration with BAS via RS‑485 Modbus or the Nexa platform through Wi-Fi.
