Cast Iron Swing Check Valve Flanged Ends
Product Details
Swing check valves non-return valve also known as check valves or check valves, its role is to prevent the flow of media in the pipeline.Open and close parts rely on the flow of media and force to open or close, in order to prevent the backflow of media valves called check valves.Check valves belong to automatic valves, mainly used for one-way flow of media on the pipeline, only allow the media to flow in one direction, in order to prevent accidents.This class of valves should generally be installed horizontally in the pipeline.
Working Principle
When fluid flows in the correct direction, the pressure pushes the disc to swing open, allowing the medium to pass through with minimal resistance. If the flow stops or reverses, gravity and back pressure cause the disc to swing back onto the valve seat, forming a tight seal and preventing reverse flow.
