A PP solenoid valve is essentially an electrically controlled valve made from polypropylene material. The solenoid coil in these valves is activated by an electrical current, which in turn opens or closes the valve to allow or stop the flow of fluid. The use of polypropylene (PP) as the material for the valve body provides a high resistance to corrosion, making it an ideal choice for systems that handle aggressive chemicals or fluids. PP solenoid valves are commonly used in applications involving water treatment, chemical processing, and food and beverage industries.
