Over pressure Protection - Rupture Discs - Pressure Relief Valves

Over pressure protection prevents the pressure in gas pipework or in gas appliances from exceeding a predetermined value. It will ensure a safe situation exists in the event of malfunction or failure of any gas pressure regulator.

What does a pressure relief valve do?

Pressure relief valves (safety relief valves) are designed to open at a preset pressure and discharge fluid until pressure drops to acceptable levels.
