DF/F Series Motor Valve is available for central air-conditioner system and opening/closing of the heating system pipe to control the temperature. The control valve is driven by the one-way magnetic sync motor. The valve is normal close when it doesn't work. When it starts to work, the thermostat provides a signal to make the motor valve work. After the valve opens, the cold or hot water will enter the fan coil to provide the cold or hot air for the room. When the room temperature reach to the setting, the thermostat will cut off the motor valves current and the return spring will close the valve to prevent the water from entering the fan coil. The room temperature can be kept that was set by thermostat by opening/closing the valve.

The driver of DF/F series motor valve is connected with the valve by the coupling. After the valve is installed, then the driver can be installed.
