Pressure Seal Check Valves are designed and manufactured in strict accordance with international standards, including API 602, ASME B16.34, or equivalent. These valves minimize flow resistance and pressure drop, making them ideal for use in horizontal positions only. The lapped disc and overlay stellite seat ensures a tight seal and long service life. The valve's disc is precisely designed, machined, and guided to provide efficient automatic shutoff even at zero pressure. Additionally, the valve features a compact structure and low-emission service, available in both swing and piston constructions.
