Rada Meynell V8/3 Thermostatic Mixing Valve

Water Regulations Advisory Scheme (WRAS) approved.

To BS 7942, BS EN 1111 and BS EN 1287.

Thermostatic mixing valve.

DZR brass.

Chrome plated.

85°C.

• Factory pre-set maximum outlet temperature: 42°C.
• Minimum temperature differential between hot inlet and pre-set outlet temperature: 10°C.
• Optimum temperature control range of mixer: 35°C to 45°C.
• Maximum hot water supply temperature: 85°C.

For safety reasons it is recommended that hot water storage temperature is maintained at between 60-65°C in ablutionary applications. The performance specification outlined below is achieved with the outlet blend temperature set between 35°C and 45°C, with supply temperature of 15°C cold and 65°C hot and nominally equal inlet supply pressure. Outlet blend water temperature is maintained within 2°C with a 10°C change in hot or cold supply. Shutdown of outlet flow to seepage within two seconds in the event of failure in either the hot or cold water supply, providing the blend temperature differs from the inlet supply temperature by at least 10°C. The valve will maintain control with a pressure loss ratio of up to 10:1.
