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.
