The PREL104005 High Capacity Potable Water Pressure Relief Valve is designed to effectively discharge water from the system when the cold water pressure exceeds the set limit, safeguarding unvented cylinders from over pressurisation. Ideal for high flow and larger capacity systems, the Reliance Valves 104 Series High Capacity Potable Water Pressure Relief Valve provides robust protection against pressure surges. Pre-set and locked to a specific pressure, this valve will lift from its seat and allow water to escape into the waste when the system pressure surpasses the threshold.

Available in a variety of pressure settings ranging from 3.5 to 8 bar, as well as multiple connection sizes, this valve offers flexibility for installation.
