Features of Stainless Steel Check Valve

H44W, H44Y stainless steel non-return valve is the medium by the pipeline itself, the flow of force generated by the automatic opening and closing, is an automatic valve. Check valve for piping systems, its main role is to prevent media backflow, to prevent the pump and its drive motor reversal, as well as the container media release. Check valves can also be used on lines where the pressure may rise to a level above the pressure of the main system auxiliary system.

The working characteristic of the check valve is that the load changes greatly, the opening and closing frequency is small, and when the input is closed or opened, the applicable period is long and the moving parts are not required to move. But once it is "switched", it must be flexible, which is more demanding than the usual mechanical movements. Since the check valve is qualitatively determined for quick closing in most practical applications, the medium is directional in the moment the check valve is closed, and the media rapidly drops from the maximum reverse speed to zero as the valve flap closes. And the pressure rises rapidly, which is a "water hammer" phenomenon that may have a destructive effect on the piping system. For high-pressure piping systems where multiple pumps are used in parallel, the water hammer problem of the check valve is more prominent. A water hammer is a pressure wave in a transient flow in a pressure pipe. It is a hydraulic shock phenomenon in which the pressure rises or falls due to a change in the fluid flow rate in the pressure pipe. The physical causes are the result of the combination of fluid incompressibility, fluid motion inertia and pipe elasticity.
