Solenoid valves are essential components in various industrial applications, controlling the flow of liquids and gases with the use of electromagnetic forces. These valves operate by opening or closing a passage when an electric current passes through a coil, creating a magnetic field that actuates the valve. Solenoid valves come in many materials, with stainless steel and plastic being two of the most commonly used types. Both materials offer unique benefits that make them suitable for different applications. This article explores the features, advantages, and typical applications of stainless steel and plastic solenoid valves, helping you choose the right type for your specific needs.
