Spring Return 220vac 60hz NPT thread Motorized Zone Valve for domestic heating system
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.
Use to control the supply of the fan coil units chilled or hot water to maintain the room temperature.
· Three type: internal thread 15mm, 20mm & 25mm.
· On/Off type, 2-way normally-closed and 3-way diverting.
· Use fully-enclosed one-way hysteresis synchronous motor, with spring return and water-proof function.
· The actuator assembles the valve body quickly and easily without the need for linkages and calibration.
