Carbon steel (CS) valves offer durability and strength, making them ideal for high-pressure and high-temperature applications in industries like oil and gas and chemical processing. Stainless steel (SS) valves provide superior corrosion resistance, making them suitable for environments with aggressive or corrosive fluids such as seawater and chemical solutions. Both CS and SS valves come in various types, including ball valves, gate valves, globe valves, and check valves, offering versatile solutions for fluid control in diverse industrial settings.
