Lift-Check Valve

A lift-check valve is a type of valve that falls under the supply class of Valves, Nonpowered in the supply group Valves.

A lift-check valve is designed to allow fluid flow in one direction while preventing backflow in the opposite direction. It consists of a disc or a piston that is lifted off its seat by the pressure of the fluid flowing in the desired direction. When the flow stops or reverses, the disc or piston is forced back onto the seat, preventing backflow.

Lift-check valves are commonly used in various industries, including oil and gas, water treatment, chemical processing, and power generation. They are typically installed in pipelines, pumps, and other systems where backflow prevention is necessary.

These valves are available in different sizes, materials, and designs to suit specific applications and operating conditions. Some lift-check valves may have additional features such as spring-loaded discs or adjustable settings to control the cracking pressure or prevent slamming.

Overall, lift-check valves are essential components in fluid systems to ensure the proper flow direction and prevent damage or contamination caused by backflow.
