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.
Setting and testing of the valve is included free of charge, along with a pressure test certificate confirming this.
If you have an existing NABIC valve that requires testing and recertifying why not try our NABIC valve test and recertify service.
Alternatively, if you require a spares kit for your valve then head to our NABIC 500 valve spares kit product page.
