A plastic solenoid valve is an electromechanical device used to control the flow of fluids or gases through a pipe or system. These valves use a solenoid to operate a mechanism that either opens or closes a passage. The body of the valve is made from plastic, which offers several advantages over traditional metal valves. Plastic valves are lightweight, corrosion-resistant, and ideal for handling aggressive chemicals and harsh environments. They are commonly used in systems where the fluid or gas is not too hot or pressurized, such as in water filtration systems, pharmaceutical equipment, and automated industrial applications.
