一.Product Introduction
J61H, J61Y type PN200~PN320 high temperature butt welding power station globe valve is suitable for nominal pressure PN200~PN320 and P54/100V-P57/170V, operating temperature ≤540℃ (of which P57/170V operating temperature is 570℃) in the pipelines of various systems of petroleum, chemical, hydraulic, and thermal power plants, cut off or connect the pipeline medium.
二.Product Features
- The middle cavity of the valve adopts a pressure self-tightening sealing structure, the better the sealing performance.Both ends of the branch pipe are welded structures.Welding bevel can be matched according to standard or user requirements
- The sealing surface of the valve disc and valve seat is made of Steely cobalt-based cemented carbide surfacing, which is wear-resistant, high temperature resistant, good scratch resistance and long service life.
- The valve stem has been tempered and surface nitrided, which has good corrosion resistance and scratch resistance.
- The depth of the valve cover packing letter is reasonable, the packing is added with corrosion inhibitor, and the sealing is reliable.
