Function of solenoid valve

How does a solenoid work? What is a normally closed solenoid valve? A solenoid valve is an electromechanical device in which the solenoid uses an electric current to generate a magnetic field and thereby operate a mechanism which regulates the opening of fluid flow in a valve. Solenoid valves differ in the characteristics of the electric current they use,. The specific purpose of a solenoid valve is expressed by its circuit function.

A solenoid valve , otherwise known as an electrically-operated valve , is an automatic valve that removes the need for an engineer to operate a valve manually.

Solenoids operate using an electromagnetic solenoid coil to change the state of a valve from open to close or vice-versa. Some samples of the utilization of solenoid valves include heating systems, compressed gas technology, industrial automation, mechanical device systems, and irrigation systems. The solenoid valve controls the flow of the fluid from inlet port to the outlet port. The outlet port is eventually connected to the process where the fluid is required.

The body of the solenoid coil is cylindrical in shape, and it is hollow from inside. Solenoids are commonly used as the switch or valves which are entirely automated. The magnetic field of solenoid also has a south and a north pole like other magnets.

It can be seen after removing the transmission pan attached to the valve body.

Generally, multiple solenoids are used in a system, and each has color-coded wires for ease of identification and replacement. Programmed water system sprinkler frameworks additionally utilize solenoid valves with a programmed controller. Three-way solenoid operated valves have three port connections and two valve seats. One valve seal always remains open and the other closed in the de-energized mode. When the coil is energize the mode reverses.

The 3-way solenoid valve shown in Fig. Usually, solenoid valves are used whenever flow of media has to be controlled automatically. In pilot-operated valves , a solenoid moves the plunger, which creates a small opening, and pressure through the opening is what operates the valve seal.

In both types, solenoid valves require a constant flow of electrical current to remain open because once the current is stoppe the electromagnetic field disperses and the valve returns to its. An electrical coil in the solenoid , and 2. A valve body or pressure vessel. The valve is the pressure containing unit that acts to shut off or open media flow. The basic principle of a solenoid valve is a force balance of the the magnetic force of the solenoid on one side, and the pressure of the medium and force of the spring on the other side.

Now solenoid valves are also fabricated with combined action of on-off valve and control valve. Just take an example of anti surge valve on an axial compressor which switches on the gas flow through the recycle line from discharge to suction in order to prevent a minimum flow at which surging takes place.
