A solenoid valve is an electrically operated device that is used to control the flow of liquids or gas through pipes and tubes. Its main part is the solenoid, which is a coil wound on a cylinder that generates a magnetic field when it is supplied with an electric current. This magnetic field acts on the valve mechanism and allows the passage to open or close for the flow of liquid or gas.

Solenoid valve definition:

A solenoid valve is an electromechanical device whose opening and closing is controlled by an electrically controlled solenoid (electromagnet).

How a solenoid valve works:

Solenoid: The main part of the solenoid valve is the solenoid - a coil wound on a roller. When an electric current passes through this coil, a magnetic field is created around it.

Magnetic action: The magnetic field of the solenoid acts on the valve mechanism, which can be controlled by its position. Depending on the particular design, this magnetic action can either open or close the fluid or gas passage.

Valve opening and closing: When the solenoid is off (no current), its magnetic field is not generated and the valve mechanism can be in a certain position that determines the state of the valve (open or closed). If the solenoid is turned on (current passes through the coil), a magnetic field is created, which acts on the mechanism and changes its position, thereby also changing the state of the valve.

Use of solenoid valves:

Solenoid valves have a wide range of uses in various industrial and commercial applications:

Plumbing: Used to control the flow of water in various systems such as water and sewage systems, sprinkler systems and automatic irrigation systems.

Gas Control: They are used to control the flow of gas in a variety of applications, including industrial processes and household appliances such as gas stoves.

Automation: In industry, solenoid valves are often used to automate processes where fast and precise flow control of liquids or gases is required.

Medical Devices: In medical devices, solenoid valves are used to control the flow of various liquids and gases as part of medical and diagnostic processes.

Automotive: In vehicles, solenoid valves can be used in a variety of systems, including emissions control, ventilation and cooling control, and other applications.

This is just a summary of the possibilities of using solenoid valves. Their use depends on the specific need and application where it is necessary to control the flow of liquid or gas.
