Thermostatically blends hot and cold water to a safe outlet temperature (TMV3 approved for healthcare)
Reliance Valves Heatguard TMV3-8 Thermostatic Mixing Valve blends hot and cold water to a constant and safe shower and bath outlet temperature to prevent scalding.
Regulating the storage temperature of water in healthcare, residential and commercial settings is increasingly common. To circulate water at a temperature of 60°C, water is typically stored and distributed at a high temperature to prevent Legionella.
The Heatguard TMV3-8 is designed to mix hot and cold water at the point of discharge to a safer and cooler temperature to prevent accidental scalding. If the cold water supply fails, the valve automatically shuts off the hot water to prevent unsafe temperatures from reaching the outlet.
Fully certified by the NSF, Heatguard TMV2-8 meets the NHS D08 specification for the TMV3 Scheme for basin, bidet, shower and high-pressure bath fill applications. It is therefore commonly specified in the healthcare sector to protect vulnerable people from scalding from high temperature water supply.
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.
