Forged Steel Check Valves are meticulously designed and manufactured in strict compliance with international standards such as API 602 and ASME B16.34, or their equivalents. These valves are engineered to minimize flow resistance and pressure drop, ensuring optimal performance. They are specifically designed to be mounted in a horizontal position. The lapped and screwed seat ring ensures a tight seal and long-lasting service. The valve's disc is precisely designed and machined to provide efficient automatic shut-off at zero pressure. These valves feature a compact structure and low-emission service, making them suitable for both swing and piston constructions.
