    Tips: How does a direct-acting solenoid valve work?

    • Working principle
      When the power is on, the solenoid coil generates the electromagnetic force to lift the closure member from the valve seat to open the valve. When the power is cut off, the electromagnetic force disappears and the spring presses the closure member on the valve seat to close the valve.
    • Characteristics
      It can work normally in the vacuum, negative pressure and zero pressure. However, the diameter normally doesn’t exceed 25mm.
