An electrically operated valve is an electromechanical solenoid valve that controls a flow mechanism, by means of the magnetic field it generates from the incoming electric current. They can use different types of electric current, generate varied strengths of magnetic field, and use different types of mechanism to regulate whatever medium is flowing, depending on its make-up. They are highly reliable, durable and compatible with most media, require low control power, and provide safe, rapid switching.
The valve mechanism can take various forms, including straightforward linear motion, a rocker or plunger action, or a pivoted-armature action such as that of a quarter-turn ball valve. It can have two ports only to regulate flow, or be designed with three or more ports so as to switch flow directions between ports. It's also possible to mount multiple solenoid valves collectively on a manifold. Electrically operated industrial valves can range in diameter from a fraction of an inch to many feet across, and play a large part in automated control processes.
Electrically operated valves can be adjusted from a remote location, or as part of an automated system, and may comprise the final elements of a control loop. Such control systems are used for the automatic regulation of flow and level processes, and can operate large valves more rapidly than any manual system. Solenoid valves are used to release, shut off, distribute or mix anything fluid, including liquids, gases and slurries. They are non-toxic, quiet and energy efficient.
