Electrical Heating Valve

DRF series electrothermal valves consist of electrothermal actuator and brass valve body
      DRF series electrothermal valves consist of electrothermal actuator and brass valve body, which are widely applicable for air conditioning system. They are used to adjust the indoor temperature by control the open/close of the pipe of chiller water or hot water and very simple to install and manintain.
 
      DRF series electrothermal valves actuator is designed to control the open/colse of the pipe of chiller or hot water for air-conditioning system so as to control the indoor temperature. Because the valve is normally closed, when it needs to work , the thermostat will provide an open signal by connecting it with the AC supply to make the actuator work, then the valve will be opened. The chiller water or hot water will enter into the fan coil to supply chiller air or hot air for room. When the room temperature reaches the set point, the thermostat will make the electrothermal actuator power off, and the spring return of the valve will close the valve and stop the water flow entering into the fan coil. Room temperature will be always kept in the range of set point temperature through the open and off the valve.

Features
1.No noise.
2.Spring return function
3.Easy screw installation.
