The NABIC 500T Combined 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. The NABIC 500T's pressure and temperature elements operate independently, thereby providing dual safety protection in the one valve. NABIC Valves now come with an Industry leading 5 Year Guarantee.

Note: *The DN value embossed on the valve body indicates the NABIC 500 body size used to make this valve and has no relationship to the inlet or outlet size. For example a valve with 1" connections (DN25) uses a DN20 NABIC 500 valve body hence will have DN20 on the side of the valve.
