Product Reference

Rada 222-T3 Thermostatic Mixing Valve (1.0.407.07.3)

Standard product features

A ¾" thermostatic mixing valve incorporating a Radatherm service-free cartridge, check valves and strainers.

Mixers are supplied with ¾" flat faced union connectors terminating in 22 mm compression connections.


Designed to be concealed in a duct or cupboard and used with a separate outlet in bathing facilities.


  • Inlet and outlet: ¾" flat faced male union.
  • Note: 2 elbows and 1 straight union connectors are supplied, terminating in 22 mm compression connections.
  • Standard connections are hot (left), right (cold).

Pressure/ Flow rates:

  • Minimum dynamic supply pressure: 0.15 bar.
  • Minimum flow rate: 3 litres/minute at mid blend.
  • Maximum flow rate: 40 litres/minute at mid blend.
  • Maximum pressure loss ratio: 10:1 (in favour of either supply).
  • Maximum dynamic supply pressure: 5 bar.
  • Maximum static pressure: 10 bar.

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

Temperature range:

  • Factory pre-set maximum outlet temperature: 43°C.
  • Minimum temperature differential blend to either supply: 12°C.
  • Optimum temperature control range: 30–50°C.
  • Minimum cold water temperature: 1°C.
  • Maximum hot water temperature: 85°C.

Note: The mixing valve can accept temporary temperature excursions above 85°C without damage, however, operation at such elevated temperatures is not recommended. 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: DZR brass nickel plated.
  • Locking shroud: White engineering plastic.
