Relief Valves: This pressure relief valve is designed to protect an unvented system from over pressurisation. The valve is pre-set and locked to a 3.5 bar. Therefore, if the system exceeds this pressure, the valve will lift off the seat and water will discharge from the valve to waste. This is the first safety devide in line within an unvented system.
Connection Sizes = 1/2″ x 15mm
Pressure = 3.5Bar
