Rada 425-T3 C Thermostatic Mixing Valve

Type 425-T3 C thermostatic mixing valve incorporates a Radatherm temperature sensor, check valves, filters and isolating ball valves and is supplied with 28 mm compression fittings.

Connections:

• Inlet: 1" BSP female or 28 mm compression fittings (adaptors supplied).

• Outlet: 1" BSP female.

• 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.

Operation:

The temperature control knob allows the user to select the required temperature within the range available. An integral temperature stop limits the maximum temperature to a pre-set 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).

Flow control:

A separate flow control is required.

Temperature range:

• Thermostatic control range: 25°C to 60°C.

• Optimum thermostatic control range: 35°C to 46°C.

• Minimum cold water temperature: 1°C.

• Maximum hot water temperature: 85°C.

Pressure/ Flow rates:

• Minimum dynamic supply pressure: 0.1 bar (0.2 bar in healthcare).

• Maximum dynamic pressure: 3.5 bar.

• Maximum supply static pressure: 10 bar.

• Minimum flow rate: 8 litres/minute at mid blend with nominally equal supply pressures.

• Maximum flow rate: 200 litres/minute.

• Maximum pressure loss ratio: 10:1 (in favour of either supply during flow).

Materials:

Body - DZR brass chrome plated.
