Pressure Sealed Check Valves are meticulously designed and manufactured in strict adherence to international standards such as API 602, ASME B16.34, or equivalent. 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-in seat ring ensures a tight seal and long-lasting service. The valve's disc is precisely designed, accurately machined, and guided to achieve efficient automatic shut-off at zero pressure. These valves feature a compact structure and are designed for low-emission service, available in both swing and piston constructions.
