The GV4303 series electric valve is used to control the opening and closing of pipes in air conditioning and heating systems to control room temperature. The control valve is driven by a unidirectional hysteresis synchronous motor with spring return. The valve is normally closed when not in operation. When needed, a thermostat provides an opening signal, connecting the electric valve to AC power and opening it to allow chilled or hot water to enter the fan coil unit, providing cooling or heating to the room. When the room temperature reaches the thermostat's set value, the thermostat de-energizes the electric valve, and the return spring closes the valve, cutting off the water flow to the fan coil unit. Through valve opening and closing, the room temperature is maintained within the thermostat's set range.

The GV4303 series electric valve can be equipped with an auxiliary switch for controlling other equipment; different pipe types and applicable voltages are available to meet various needs.

The GV4303 series electric valves are flexible in operation, reliable and durable, with low operating noise, and can withstand the high temperature and high humidity environment often found in concealed fan coil units.
