Adamant valves offers solenoid valves, including pneumatic solenoid valves. They are electromechanically operated by running an electric current through a solenoid.

A solenoid valve is an electromechanically controlled valve. The valve features a solenoid, which is an electric coil with a movable ferromagnetic core in its center. This core is called the plunger. 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 a force on the plunger. As a result, the plunger is pulled toward the center of the coil so that the orifice opens. This is the basic principle that is used to open and close solenoid valves.
