Stainless steel diaphragm valves generally employ 316L stainless steel for the valve body containing 16–18% chromium, 10–14% nickel, and 2–3% molybdenum, which provides excellent resistance to chlorides and acids. The diaphragm is typically constructed of PTFE, EPDM, or silicone for flexibility and chemical resistance. Working pressures up to 10 bar, and temperatures –20°C to 180°C, depending on the material of the diaphragm. These valves are outstanding weldable, surface finish (Ra ≤ 0.4 µm), and resistant to corrosion and media entrapment. They are configured for fulfilling cleanroom, sterile, and high-purity fluid control applications.
