What does DDF-G do?

DDF-G series motorized valve are available for controlling the central air conditioning and heating system's opening and closing to control the room temperature. The control valve is driven by the unidirectional hysteresis synchronous motor and adopts spring reset. The actuator is normally closed when it doesn't work. If it needs to work, the thermostat will provide a signal of opening, and then the actuator will get the power to work. Opening the valve, the cold and hot water will come into the fan coil to provide the cold or hot air. When the set temperature is achieved,

the thermostat will cut off the electric thermal valve's power, and then the reset spring can close the valve to stop the water flow into the coil. So the room temperature is always maintained within the set range by thevalve's opening and closing. DDF-G series motorzed valve actuator and valve is connected by thread. Actuator should be installed after the valve. The installation is

very convenient. Actuator installation should be close to the wall to save space. This product has high durability andsmall noise, and can be used in the secluded fan coil which is always has high temperature and humidity.
