Product Reference
Rada 320 IC Thermostatic Mixing Valve (1.1847.013)
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: 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.
