• Flow Direction: The valve ensures unidirectional flow, automatically closing when flow reverses to prevent backflow.
• Seals: NBR, EPDM, Viton, or PTFEseals are used, depending on fluid and temperature conditions.

The GB Swing Check Valve operates using a swing-type disc mechanism. When the fluid flows in the correct direction, the disc lifts off the valve seat, allowing fluid to pass through the valve. When the flow direction reverses, the disc swings back into place, sealing the valve and preventing any backflow. This automatic operation ensures that the valve effectively controls the flow of fluid and prevents reverse flow without the need for manual intervention.
