Valve solution to prevent media backflow

摘要

A new generation of check valves from GF Piping Sys-tems aims to help prevent failure-free backflow of media. Check valves, in particular, are subject to many wear factors: mechanical stress because of high flow velocities, water hammer in the pipeline and chemical attack on the valve components, such as elastomer seals. This can have serious consequences on process control, said GF, beginning with a small leak caused by swelling of the elastomer seal to valve components becoming jammed and finally total breakdown of the valve.
