What is a solenoid valve used for?

A solenoid valve is an electromechanical device used to control the flow of liquid or gas. It uses a coil of wire that, when energized, creates a magnetic field that pulls a plunger or valve mechanism to open or close the valve. Solenoid valves are commonly used in a wide range of applications, including irrigation systems, refrigeration, heating and cooling systems, car washes, medical equipment, and many others. They are often used to automate the process of controlling fluid flow and can help increase efficiency and reduce labor costs.
