Temperature & Pressure Relief Valves

Safeguard water heaters against pressure extremes. These valves discharge water when the pressure or temperature exceeds a set level to help prevent overpressurization.

Standard Installations

Provide emergency relief for both excessive temperature and pressure for domestic hot water heaters and tanks. These valves have bonnet screws that resist tampering.
