• Pressure Rating: Suitable for use in systems with pressure ratings up to PN16or higher, depending on material and application.
• Temperature Range: Designed for operation in temperatures ranging from -10°C to 150°C, with options available for higher temperatures as needed.
• Material: Constructed from carbon steel, stainless steel, cast iron, and other materials, depending on the application and environment.
• Connection Type: Available with flanged, butt-weld, and socket-weld connectionsto fit various pipeline installations.
• Flow Direction: The valve permits unidirectional flowand automatically closes to prevent backflow when the direction of flow changes.
• Seals: Seals are available in various materials such as NBR, EPDM, Viton, and PTFE, depending on fluid and temperature conditions.

The GB Lift Check Valve operates by utilizing a spring-loaded lift-type mechanism that responds to changes in fluid flow direction. When the fluid flows in the proper direction, the disc or valve element lifts off the valve seat, allowing the fluid to pass through. When the flow reverses, the valve element automatically falls back onto the seat, creating a seal that prevents any backflow. This automatic operation ensures that the valve effectively controls fluid flow without the need for manual intervention.
