2-way and 3-way 3/4" Electric Valve Motorized Control Zone Valve
SKC series brass motorised valves are primarily designed to control the flow of water or steam in response tothe demand of a controller in zone and fan coil applications.The valve is driven by hysteresis synchronous motor with spring return. The valve is normal-closed. When thethermostat is working, it will provide an opening signal, and the motorized valve will be turned on to open. Thenthe chilled/hot water will enter into the coil and supply the cold/hot to the room. When the room temperature risesup to the set point, the thermostat will make the valve power off. At the same time the valve will be closed byreturn spring and the water to the coil will be shut off. The room temperature will be kept in the setting range all the time through the opening and closing of the valve.
