Forged Steel Check Valves are designed and manufactured in strict compliance with international standards such as API 602, ASME B16.34, or equivalent. These valves are engineered to minimize flow resistance and pressure drop, ensuring efficient performance. They are specifically designed for horizontal installation only. The lapped and screwed seat ring guarantees a tight shutoff and long service life. The valve's disc is precisely designed, accurately machined, and guided for reliable automatic shutoff at zero pressure. These valves feature a compact structure and low emission service, available in both swing and piston constructions.
