Product Reference

Rada V12 Exposed Thermostatic Shower Valve (1.1651.001)

Standard product features


  • Inlets: 15 mm compression.
  • Outlet: ½” BSP Flat Face/ 15 mm compression.
  • Standard connections are: hot- left, cold- right, outlet- bottom or top.


The Rada V12 is operated via a single sequential control which when rotated initially opens the valve, then increases temperature from cold to a pre-set maximum.

Temperature Range:

  • Temperature range from cold to preset maximum.
  • The maximum temperature that can be selected is factory set at approximately 43°C, but this can be reset on site if required (by an authorised person).
  • Thermostatic control ± 1°C within the range 35–45°C (assuming supplies of 15–65°C hot at nominally equal pressures).

Note: In the event of loss of either supply, the valve will automatically shut off. Minimum temperature differential of blend to either supply 10°C.


  • Cold water temperature range 5–25°C.
  • Hot water temperature range (recommended) 60–65°C.
  • Maximum hot water temperature 85°C.

Note: For reasons of general safety, hot water storage temperatures should be maintained at between 60–65°C where serving ablutionary applications. The mixing valve can accept temporary excursions above 85°C without damage, however operation at such elevated temperatures is not recommended.


Dynamic supply pressure (Running):

  • Minimum: 0.1 Bar.
  • Maximum: 5 Bar.
  • Maximum Static: 10 Bar.
  • For optimum operation the inlet pressures should be nominally equal.
  • Maximum Pressure loss Ratio should not exceed 10:1 in favour of either supply during flow.


  • Body and Elbows: Chrome Plated Polished Brass.
  • Lever: Chrome Plated Zinc Die Casting.
