Forged Steel Check Valves are designed and manufactured in accordance with international standards such as API 602, ASME B16.34, or their equivalents. These valves are optimized to minimize flow resistance and pressure drop, ensuring efficient performance. They are suitable for installation in horizontal positions only. The valve features a lapped and screwed seat ring, ensuring tight shut-off and extended service life. The disc is precisely designed, machined, and guided to provide efficient automatic shut-off at zero pressure. Available in both swing and piston constructions, these valves offer compact structure and low-emission service.
