Discharges water off the system at a set pressure in the event of cold water over pressurisation to a unvented cylinder

Reliance Valves 107 Series Potable Water Pressure Relief Valve is designed to protect an unvented system from over pressurisation. The valves are pre-set and locked to a particular pressure, and if the system exceeds this pressure the valve will lift off the seat and water will discharge from the valve to the waste.

This is the first safety device in line within an unvented system. The valves are available in pressures ranging from 3.5 – 6 bar, as well as multiple connection sizes to allow for flexible installation.
