Check valves are usually fabricated out of 304 or 316 stainless steel with tensile strengths between 520–580 MPa and excellent resistance to corrosion, especially in wet and slightly acidic conditions. 316 has more resistance to chlorides and sea conditions as a result of having 2–3% molybdenum content. They are made for working pressures between 150–1000 PSI and temperatures between –30°C to well above 200°C. Mechanical strength and corrosion resistance provide a long service life in flow-critical applications. Their internal moving components (discs, springs) are also made of wear-resistant stainless steel.
