Product introduction
DF-04 internal thread motorized valve is available for central air conditioning and heating system’s opening and closing. Control valve depends on the one-way Magnetic synchronous motor to reset spring. When it is working, the thermostat gives a signal of opening. 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.
Motorized valve adopts thread motorized valve joint. It has flexible operation, high durability and small noise.
