on/off Two Position Motorized Zone Valve and Spring Return Actuator
SKCF 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.
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.
