ASTM A182 F22 Lift Check Valve, API 602, CL1500, PSB, Custom

Key Specifications / Features

The ASTM A182 F22 Lift Check Valve Plant offers high-performance valves designed to API 602 standards. These valves are made from forged alloy steel, ensuring strength and durability. They are available in custom sizes to meet specific needs and feature a Class 1500 LB (PN250) pressure rating for high-pressure applications. The extended body and pressure seal bonnet design enhance performance and reliability. The valves are equipped with welded ends for secure and durable connections.

Pressure Sealed Check Valves are designed and manufactured in strict compliance with International Standards such as API 602, ASME B16.34, or their equivalents. These valves are engineered to minimize flow resistance and pressure drop to the greatest possible extent. They are specifically designed to be mounted in a horizontal position only. The lapped and screwed-in seat ring ensures a tight shut-off and long service life. The valve’s disc is perfectly designed, accurately machined, and guided to achieve efficient automatic shut-off at zero pressure. These valves feature a compact structure and are suitable for low-emission service. They are available in both Swing and Piston constructions.
