Stainless Steel Check Valve DN300 For Industrial With Customized Packing

Product Feature

The working characteristics of stainless steel check valves are large load changes, low opening and closing frequency, and long service life once they are closed or open, and no moving parts are required to move. However, once there is a "switching" requirement, it must be flexible, which is more demanding than common mechanical movements. Since check valves are qualitatively determined to be used for rapid closing in most practical uses, and at the moment the check valve is closed, the medium flows in one direction, and as the valve disc closes, the medium quickly drops from the maximum backflow speed to zero, while the pressure rises rapidly, which produces a "water hammer" phenomenon that may have a destructive effect on the pipeline system.
