Standard product features

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.
