Solenoid valve bodies are typically made from materials such as brass, stainless steel, plastic, and aluminum. Brass is commonly used due to its good corrosion resistance, machinability, and cost-effectiveness, making it suitable for water, air, and light oil applications. Stainless steel is chosen for its superior corrosion resistance, strength, and durability, ideal for aggressive or high-pressure environments, including chemical and food processing industries. Plastic, such as PVC or nylon, is lightweight and resistant to corrosion and chemical attack, making it suitable for applications involving corrosive fluids or where weight is a concern. Aluminum is used for its lightweight and good thermal conductivity, often in applications where weight reduction is critical. Each material is selected based on the specific requirements of the application, including the type of fluid, pressure, temperature, and environmental conditions.
