CRYO
Plunger or lift check valves are designed to prevent backflow of fluids and are commonly used on cryogenic bulk stations and pipelines. Their close-off ability prevents compressors and centrifugal pumps from operating in reverse if power is lost which is why they are usually installed next to those devices.
Self-actuated valves like lift check valves use gravity and the pressure of the product to operate. This feature ensures the valve closing off when undesired back-flow occurs.
