  • The pilot-operated solenoid valve is usually used in big diameter and high pressure occasions. As
    the valve is open, the minimum pressure of the solenoid valve is not allowed to be lower than 0.05MPa. So, the pilot pressure is required, otherwise it cannot be opened. In addition, the flow capability of the pilot-operated solenoid valve is bigger than that of the direct acting solenoid valve. It has a relatively higher requirement to the purity of the compressed air. Instead, the directly operated solenoid valve has no such high requirement.

  • A proportional valve provides a change in output pressure or flow in the same ratio
    as the change in the input, for example if the input doubles then the output will also double. Proportional valves can be interconnected with the output from one being used as the input to another.

  • Solenoid valve is an electrically controlled valve. The valve features a solenoid, which is an
    electric coil with a movable ferromagnetic core (plunger) in its center. In the rest position, the plunger closes off a small orifice. An electric current through the coil creates a magnetic field. The magnetic field exerts an upwards force on the plunger opening the orifice. This is the basic principle that is used to open and close solenoid valves.
