The Caleffi range of safety relief valves are WRAS approved and are designed to protect hot water cylinders and boilers in domestic hot water and heating systems. Valves are set to a certain pressure (bar g) and when the system reaches this pressure the valve is designed to open to release the pressure ensuring the system does not exceed its maximum safety limits.
