    Tips: Working principle and characteristics of pilot-operated solenoid valve

    • Working principle
      When the power is on, the electromagnetic force opens the pilot hole and the pressure of the upper chamber decreases rapidly, forming a pressure difference which is low in the upside and high in the bottom around the closure element. The fluid pressure promotes the closure element to move upwards to open the valve. When the power is off, the spring force closes the pilot hole. The pressure through the bypass port rapidly forms a pressure difference which is high in the upside and low in the bottom around the closure element. The fluid pressure drives the closure element to move downwards and close the valve.
    • Characteristics
      The fluid pressure scope has a relatively high upper limit. It can be installed randomly, with the fluid pressure difference condition being satisfied.

    This video shows how ATO 24V DC water solenoid valve is operating internally, and tells you it is a good solenoid valve by testing the solenoid voltage with a multimeter.

    This water solenoid valve works well...
    This water solenoid valve works well with 24V DC on an auto water-fill system. The port size G1/2 inch is really what I needed. There is no problem for installation. It doesn't leak for now.
