DDF-K Series Motorized valves are used to control the flow of hot water, freezed water in heating, cooling or air-conditioning applications, so as to control room temperature indirectly. It is made up of Actuator and Valve Body. The thermostat(NTC) transfers a signal to actuator that will connect to power, and then open valve, input hot water or freezed vater to fan coil unit; if the room temperature reaches to set-point, thermostat transfers a signal to actuator to cut off the power, and spring switch returns, valve is closed, sothat the hot or freezed water is block to fan coil unit.
