Egret series HVAC solenoid valve is an electromechanical valve, used to control the refrigerant or water autonomously and remotely in the air conditioning system. There's a solenoid coil on the top, which is used for controlling the valve by passing an electrical current thru it. In the meantime, HVAC liquid line solenoid valve will create an electromagnetic zone, thus, to control the valve. In other words, there's no need of engineer to physically operate, the HVAC solenoid valve will do autonomously. As a result, it will save a lot of labor, and make the system running more safely & efficiently. In general, you can find solenoid valve in many industries, washing machines, HVAC, etc.

Working Principle of HVAC solenoid valve

A solenoid valve furnace consists of three key parts

Solenoid coil: This coil, when energized with electricity, creates a magnetic field.

Plunger: This metal core sits inside the coil and moves up and down when influenced by the magnetic field.

Valve seat: This opening controls the flow of gas. It's connected to the plunger and opens or closes depending on its position.

The Magic of Magnetism

When you turn on your thermostat and demand heat, the control board sends an electrical current to the solenoid coil. This current energizes the coil, generating a magnetic field. The magnetic field, in turn, pulls the plunger upwards, lifting it away from the valve seat. This opens the valve, allowing gas to flow freely through the system and ignite the burner, ultimately warming your home.

When the Heat Fades

Once the desired temperature is reached, the thermostat sends a signal to the control board, cutting off the power to the solenoid coil. The magnetic field disappears, and the plunger, under the influence of a spring or gravity, returns to its original position, closing the HVAC liquid line solenoid valve and stopping the flow of gas.
