Forged Steel Check Valves are designed and manufactured in strict accordance with international standards such as API 602, ASME B16.34, or equivalent. These valves are engineered to minimize flow resistance and pressure drop, making them ideal for horizontal installation. The lapped and screwed-in seat ring ensures a tight shutoff and extended service life. The valve's disc is precisely designed, machined, and guided to provide efficient automatic shutoff even at zero pressure. These valves feature a compact structure and low-emission service, available in both swing and piston constructions.
