500T – Nabic Temperature & Pressure Safety Relief Valve
The 500T pressure & temperature relief valve has been designed for use on unvented hot water supply systems, where protection against excess temperature is required in addition to pressure protection. Pressure and temperature elements of the valve operate independently, thereby providing dual safety protection in the one valve. Supplied set to your requirements with a certificate confirming lift pressure at no additional cost.
