Semi-direct acting solenoid valve

Semi-direct acting solenoid valve

●Material and Structure:

○The valve body is usually made of high-quality metal materials such as stainless steel and brass, which possess excellent corrosion resistance and mechanical strength.

○The sealing components are made of high-performance rubber or plastic materials to ensure the sealing performance of the valve and prevent the leakage of the medium.

○The electromagnetic coil uses high-purity copper windings, with excellent insulation properties, and can maintain stable electromagnetic force during long-term operation.

Working principle

● Low-pressure startup stage: When the system pressure is low, the operation mode of the solenoid valve is similar to that of a direct-acting solenoid valve. After being energized, the electromagnetic coil generates electromagnetic force, which directly acts on the valve core, overcoming the spring force and the medium pressure, causing the valve core to move upwards and opening the valve, allowing the medium to flow.

● High-pressure operation stage: When the system pressure increases, the solenoid valve operates using the pilot principle. The electromagnetic force first opens the pilot hole, creating a pressure difference between the upper and lower chambers of the main valve. Under the effect of this pressure difference, the main valve core is pushed, thereby enabling the valve to open. When the power is cut off, the electromagnetic force disappears, and the valve core is reset by the spring force and the medium pressure, closing the valve.
