Forged Steel Check Valves are engineered and manufactured in strict accordance with international standards such as API 602 and ASME B16.34, or their equivalents. These valves are designed to minimize flow resistance and pressure drop and are intended for horizontal installation only. The lapped and screwed-in seat ring ensures a tight seal and extended service life. The valve disc is precisely designed, accurately machined, and well-guided to enable efficient automatic shut-off at zero pressure. Available in both swing and piston (lift) configurations, these valves feature a compact structure and are suitable for low-emission service.
