DDF-K seires Motorized Valve

DDF-K series motorized valve is available for central air conditioning and water heating system 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 to opening, the actuator will get the power to work. Opening the valve, the cold or hot water will come into the fan coil to provide the cold or hot air. When achived the set temperature, the thermostat will cut off the actuator '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 a comfortable range by the valve's opening and closing. The actuator and valve is connected by coupling connection way. Actuator should be installed after the valve. The installation is very convenient. Actuator installation can be close to the wall to save space. The operating noise is very low. The motorized valve is durable and reliable.
