Meynell 15/3 Thermostatic Mixing Valves

Meynell 15/3 Thermostatic Mixing Valves

A ½" thermostatic mixing valve with integral check valves and strainers, suitable for under-basin installation and providing thermostatic shutdown in less than 2 seconds.

The unit also incorporates tamper proof temperature adjustment.


  • Designed to be installed into the supply pipework and must be used with a separate outlet flow control such as a tap.


  • Inlet and outlet: 15 mm compression fittings.


  • Minimum operating pressure: 0.1 bar.
  • Maximum static pressure: 10 bar.
  • Maximum pressure loss ratio: 10:1 (in favour of either supply).
  • Maximum hot water supply temperature: 85°C.
  • Maximum cold water supply temperature: 25°C.

Note: Both hot and cold pressures should be nominally equal.

Temperature range:

  • 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: 35–45°C.
  • Maximum hot water temperature: 85°C (for safety reasons it is recommended that the hot water storage temperature is maintained at between 60°C and 65°C in ablutionary applications).

Body Materials:

  • DZR brass housed in white plastic casing.
