Eco 3 Port Mid Position Motorised Valve 28mm Tp Mid28

The ECO mid position motorised zone valve is supplied with 28 mm compression fittings. It is to be used for the flow control of central heating or hot water in Y-plan central heating systems. The valve operates in conjunction with inputs from a room thermostat or a cylinder thermostat. It will open only when in demand from the thermostat with the action of a geared synchronous motor and close with a spring return mechanism. When the valve is in the open position, a limit switch operates to switch on the heat source. This regulates flow for both hot water and central heating at the same time.
