Rada 425 IC Thermostatic Mixing Valve

Product Reference

Rada 425 IC Thermostatic Mixing Valve (1.1847.005)

Standard product features

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

Connections:

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.

Approvals:

WRAS approved (Water Regulations Advisory Scheme).

Operation:

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).

Materials:

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

Temperature range:

• Optimum thermostatic control range: 38°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 3.5 bar, which equates to maximum 200 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: 8 L/min at mid-blend with nominally equal supply pressures.

• Maximum flow rate: 200 L/min.

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