Discharges water to prevent cylinder damage from excess high temperature or pressure

Reliance Valves Temperature & Pressure Relief Valves are compact pressure and temperature relief valves. The valve protects against over pressurisation, which can occur within an unvented hot water system if the input temperature or pressure controls fail.

The valves are designed to be installed directly to the upper portions of a hot water cylinder, as this is where the hottest temperature is found. If the system rises above 95°C, the wax mixture within the element of the temperature probe will expand lifting the valve off its seat and releasing water to the waste, reducing the pressure within the cylinder. If the water pressure increases (without temperature increase), the valve will stay closed until the set pressure of the relief mechanism is reached, at which point the valve will again open and the excess pressure is relieved. Some models come complete with a PTFE coating on the MBSP inlet thread that can save valuable time during installation.
