Ductile Iron Swing-type Flanged Check Valve

This is a ductile iron swing-type flanged check valve suitable for fire protection and industrial scenarios, finished with standard fire-protection red coating. As a self-actuating valve, its core function is to allow fluid to flow in only one direction, automatically preventing reverse flow (backflow) in a pipeline — this ensures system pressure stability and equipment safety. The flanged connection design enables quick installation and maintenance; it is compatible with high-pressure fire protection and industrial fluid transfer applications, serving as a common protective valve in fire engineering and industrial piping systems.
