Standard product features

Suitable for surface-mounted, medium to large group showering installations.


Standard connections are hot - left, cold - right, outlet - top when facing the control. Note: The outlet can be altered to bottom outlet if required by repositioning the drain plug.


WRAS approved (Water Regulations Advisory Scheme).


The temperature control knob allows the authorised user to select the required temperature within the range available. An integral temperature stop limits the maximum temperature to a present level and can only be reset by an authorised person (alternatively, the temperature knob can be locked in position after the desired temperature has been selected).


Body: European 4MS Scheme Compliant Brass meeting DZR and Low Lead requirements.

Temperature range:

  • Optimum thermostatic control range: 30°C–50°C.
  • Minimum cold water temperature: 1°C.
  • Maximum hot water temperature: 85°C.

Pressures/ flow rate:

  • Minimum dynamic supply pressure: 0.1 bar.
  • Maximum supply static pressure: 10 bar.
  • Maximum pressure loss ratio: Should not exceed 10 : 1 in favour of either supply during flow.
  • Maximum pressure loss: Inlets to outlet is 5.6 bar, which equates to maximum 120 L/min flow rate at mid-blend.

Note: Pressure loss is the pressure drop between the inlets and the outlet of the mixing valve when flow is taking place.

  • Minimum flow rate: 6 L/min at mid-blend with nominally equal supply pressures.
  • Maximum flow rate: 120 L/min (5.6 bar pressure loss).

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