【Usage】 
 J61H, J61Y type PN200 ~ PN320 hot butt welding plant cut-off valves for nominal pressure PN200 ~ PN320 and P54/100V-P57/170V, temperature ≤ 540 ℃ (including P57/170V operating temperature of 570 ℃) of petroleum, chemical, water, fire station in a variety of system piping, cut off or connected to the pipeline media. 

 [Features] 
 1, the valve chamber by pressure from tight seal structure, the better the sealing performance. Welded at both ends of the branch structure. Welding groove can be connected with standard or user requirements 
 2, valve, valve seat sealing surface using cobalt-based alloy stellite surfacing made of wear-resistant, high temperature, anti-abrasion performance and long service life 
 3, stem quenched and nitrided surface, good corrosion and scratch resistance out. 
 4, valve cover reasonable depth of stuffing, packing plus inhibitor, reliable sealing
