Thermostatically blends hot and cold water to a safe outlet temperature (TMV2 & TMV3 approved for public and healthcare sectors)
Reliance Valves Heatguard Dual TMV2/3 Thermostatic Mixing Valve is TMV2 and TMV3 approved for basin, bidets, showers and high-pressure bath fill applications. Fast and simple to install, the valve blends hot and cold water to a constant and safe outlet temperature to prevent scalding.
Water is commonly stored at high temperatures to prevent Legionella. To protect end users from accidental injuries, the Heatguard Dual mixes hot and cold water at the point of discharge to a safer and cooler temperature. If the cold water supply fails, the valve automatically shuts off the hot water to prevent unsafe temperatures from reaching the outlet.
Fully compliant with the NHS model engineering specification code D08 and BSEN 1111, Heatguard Dual is the ideal choice for environments where user protection is a priority.
There are two options available: the 2-in-1 valve comes complete with strainers on both inlets and check valves, whereas the 4-in-1 also includes test ports and isolation valves.
