Thermostatic Mixing Valves

These 15mm and 22mm thermostatic mixing valves are designed primarily for single outlet use. They deliver safe, blended hot water to taps, showers, bidets and other water outlets making them ideal for use in hospitals, schools and leisure centres. The element that controls the temperature of the mixed water discharging from the valve works proportionally on both hot and cold water supplies in order to maintain the temperature of the mixed water discharged.

The thermostatic mixing valve has been independently tested and approved by the TMV3 scheme as a type 3 valve under the requirements of the NHS MES - D08 and approved by Buildcert as meeting the requirements of the TMV2 scheme. It has been specifically designed and manufactured to meet the general requirements of:
