GV4043 Series switch electric valves are applied to control room temperature by controlling the switch on and off for the central air conditioner system and heating system pipe. The control valve is driven by one-way synchronous machine of stagnant magnetism and it is spring reset. The valve is closed when it stops working. While it works, the temperature control will give out an open signal. Then the electric valve will put through the alternating current to open the valve. The cold or hot water will then flow into the fan coil to supply the cool or heat for the room. When the room temperature reaches the set temperature, the temperature control will let the electric valve cut off the power. And the return spring closes the valve to prevent the water from flowing into the fan coil. Opening or closing the valve always keeps the room temperature in the range set by the temperature control.

GV4043 Series electric valve can compose with the supplementary switch optionally to apply to the other control equipment. It has different means of pipe connection and applicable voltage to satisfy different needs.

GV4043 Series electric valve has low working noise and easy to operate. It can also resist the environment of high temperature and high humidity caused by the hidden fan coil device
