Forged Steel Check Valves are engineered and fabricated to meet rigorous international standards, including API 602, ASME B16.34, or their equivalents. Designed to reduce flow resistance and minimize pressure drop, these valves ensure efficient and reliable operation. They are intended exclusively for horizontal installation. The lapped and screwed seat ring guarantees a secure shut-off and extended service life. The valve disc is meticulously designed, precisely machined, and guided for smooth, automatic shut-off at zero pressure. Available in both Swing and Piston designs, these valves offer a compact structure and low-emission performance.
