The PREL102042 Potable Water Pressure Relief Valve is essential for managing cold water overpressurisation in unvented cylinders. Part of the Reliance Valves 102 Series, these Potable Water Pressure Relief Valves are specifically designed to protect unvented systems from excessive pressure. Each valve is pre-set and locked to a designated pressure; should the system exceed this pressure, the valve will effortlessly lift off its seat, allowing water to discharge safely into the waste system. Serving as the first line of defence in unvented installations, these valves are engineered with a single-piece cartridge for reliability and ease of maintenance. They are available in various pressure settings from 3.5 to 8 bar and come with multiple connection sizes to facilitate versatile installations.
