Isolant electric valves are primarily used in central air conditioning hot and cold water systems and heating systems. They precisely control the flow of cold and hot media as needed, preventing drastic temperature changes and achieving real-time precise room temperature control. The control valve is driven by a bi-directional motor. The motor is connected to the thermostat through common, open, and closed terminals. The thermostat continuously samples and processes on-site data, sending control signals to operate or stop the motor, thus controlling the opening degree of the electric valve. Cold or hot water enters the fan coil unit, providing cooling or heating to the room. When the room temperature reaches the set value on the thermostat, the thermostat cuts off the power to the electric valve, ensuring the valve’s opening degree remains in an optimal state, keeping the room temperature within the set range of the thermostat.
