A solenoid valve is an electromechanically operated valve that controls the flow of liquids or gases. Its primary function is to open, close, or regulate the flow of a medium through a pipe, which is activated by an electric current. Solenoid valves are crucial in sectors such as water treatment, HVAC systems, pharmaceuticals, food processing, and even in automotive applications. The materials used to manufacture these valves—stainless steel and plastic—offer unique benefits for different applications, and companies like Meishuo are leading the charge in producing reliable, long-lasting, and cost-effective solutions.
