Stainless Steel Check Valves are commonly made from SS 304 or SS 316. These materials contain 18–20% chromium, 8–14% nickel, and 2–3% molybdenum in the 316 version for improved corrosion resistance. The valves have a tensile strength of 515 to 620 MPa and resist chemical damage and high temperatures. They come with a spring-loaded or swing-type mechanism that automatically closes when the flow reverses. This feature protects pumps and piping systems. The stainless steel body assures structural integrity, requires low maintenance, and provides reliable sealing performance in both horizontal and vertical installations, even under tough operating conditions.
