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

 【Features】 
 1, the valve in the cavity by pressure from the tight seal structure, sealing the better the performance. Branch pipe ends for welding structure. Welding groove can be connected with standard or user requirements 
 2, valve, valve seat sealing surface is stellite surfacing made of cobalt-based alloy, wear resistance, high temperature, anti-abrasion performance and long service life 
 3, stem quenched and the nitrogen treatment, with good corrosion and scratch resistance out. 
 4, valve cover reasonable depth of stuffing, packing plus inhibitor, reliable sealing
