Standard product features

The Rada 215-T3 BC thermostatic mixing valve is supplied with integral strainers, check valves and a Radatherm service-free cartridge.

Units incorporate swivel elbows with 15 mm compression connectors, which can be converted to ½" BSP union if required.

The thermostatic mixing valve is approved for use in all UK healthcare premises.


  • Inlet and outlet - ½" BSP external union or 15 mm compression fittings.
  • Standard connections are hot-left, cold-right, outlet-top, when facing the control.


The mixing valve does not have integral flow control: appropriate provision must be made for this in the outlet pipework.

Temperature range:

  • Factory pre-set maximum outlet temperature: 43°C.
  • Minimum temperature differential, blend to either supply: 12°C.
  • Optimum thermostatic control range: 30°C to 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 of the mixing valve at such elevated temperatures is not recommended. For reasons of general safety, hot water storage supply temperatures should ideally be maintained at between 60°C and 65°C where serving ablutionary requirements.

Pressure/ Flow rates:

  • Minimum dynamic supply pressure: 0.15 bar.
  • Maximum dynamic supply pressure: 5.0 bar.
  • Minimum flow rate: 3 litres/minute at mid blend.
  • Maximum flow rate: 35 litres/minute at mid blend (which equates to a maximum pressure loss of 1.8 bar).
  • Maximum pressure loss ratio: 10:1 (in favour of either supply).
  • Maximum static pressure: 10 bar.


Body - DZR brass nickel plated.
