Check valves are installed in pipelines to prevent backflow. A check valve is a one-way valve to avoid damage to pipelines valves and compressors. It permits unrestricted fluid flow in one way while deactivating to prevent flow in the opposite direction. A check valve can be installed in a vertical pipe path if the flow direction is upward.
Vertical installations must be mounted. Depending on the design requirements, check valves are available in various materials. It includes brass bronze plastic and metal. This article examines the leading suppliers of check valves.
