Product introduction
DRF electric heating valves are available for central air conditioning and heating system’s opening and closing. Control valve depends on the ceresin wax propeller to reset spring. When it is working, the thermostat gives a signal of open. Then the motorized valve has power to activate. The cold and hot water come into the fan coil for providing cold or hot air. The motorized valve will stop, and at the same time the water can not flow into the coil when the set temperature is achieved. So the room temperature is maintained.
Feature
DRF electric heating valve adopts ceresin wax propeller. There is no noise during PTC heating actuation working. It has spring reset function. After the power is off, the valve is closed and the running place will be instructed by indication. The screws installation is very easy, fast and convenient.
