NABIC 520 High Lift Double Spring Safety Valve

The Reliance Water Controls (RWC) TPR15 Pressure and Temperature Relief Valves are compact yet robust solutions, expertly designed to safeguard against over-pressurisation in unvented hot water systems. These essential valves are specifically intended for installation at the upper section of a hot water cylinder, where the highest temperatures are typically encountered. In the event that the system temperature exceeds 95°C, the wax mixture within the temperature probe's element expands, lifting the valve off its seat to release water safely, thereby alleviating pressure within the cylinder. Furthermore, if water pressure escalates without a corresponding temperature rise, the valve remains shut until the predefined pressure of the relief mechanism is reached, at which point it will open to release excess pressure. Certain models feature a PTFE coating on the Male BSP inlet thread, facilitating a quicker and more efficient installation process.
