Pressure Sealed Check Valves are designed and manufactured in strict compliance with international standards such as API 602, ASME B16.34, or equivalent. These valves are engineered to minimize flow resistance and pressure drop, making them highly efficient. They are suitable for horizontal installation only. The lapped and screwed-in seat ring ensures a tight seal and long-lasting service. The valve's disc is meticulously 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.
