A replacement Mid-position motorised zone valve actuator. 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 sychronous motor and closes by a spring return mechanism. When the valve is in the open position, a limit switch operates to switch on the heat source. By doing this it regulates flow simultaneously for hot water and central heating. Please note that this valve must be installed according to the direction of the flow as indicated by the arrow on the valve body. It is only suitable for open vented or sealed pumped systems. The valve comes with a 5 core colour coded flexible cable at a length of 1 metre for ease of installation. Power consumption of hte unit at 6W, with a temperature range of 5°C to 88°C and a maxiumum differential pressure of 1 Bar. The synchronous motor in this replacement actuator is replaceable.
