Forged Steel Y Type Piston Check Valve

Check valves are mechanical valves that permit gases and liquids to flow in only one direction, preventing process flow from reversing. They are classified as one-way directional valves. Fluid flow in the desired direction opens the valve, while backflow closes the valve.

Application


 For valves which size is smaller than 2"(DN50), forged steel valves are recommended. Compared with castings,forged valve offer the advantages of more uniform structure, greater density, higher strength integrity, enhanced dimensional characteristics and closer dimensional tolerances.Owing to so many advantageds,the forged valve can be widely used in the fields of petroleum,natural gas,chemical,power and other industries.
