Home > Stainless Steel Check Valves
Harshita Stainless is a reputable provider of Stainless Steel Check Valves from Delhi, India. The valves permit single-direction flow, inhibiting backflow and safeguarding pipeline systems. Fabricated in swing, lift, and wafer designs, they are made in stainless steel alloys such as 304, 316, and 316L. Constructed to meet API, ANSI, and DIN specifications, our check valves provide minimal pressure drop, consistent seating, and extended service life. Suitable for piping systems in oil & gas, water treatment, and food processing industries, Harshita Stainless provides reliable performance in India.
Constructed from SS 304/316/316L, these valves incorporate chromium (18–20%), nickel (8–12%), and molybdenum in 316 for superior corrosion resistance. They feature tensile strength of 500–700 MPa and yield strength of 200–300 MPa. Tight sealing and low leakage are provided through precision-machined internals. Featuring hardened seats and sturdy body design, they are resistant to vibration, pressure shocks, and corrosion, providing secure protection against backflow in vital systems.
