Z961Y-P54100V,Z961Y-P54140V,Z961Y-P54170V high temperature and high pressure electric power station gate valves:electric,butt welded connection form,rising stem wedge rigid single gate valve,valve seat sealing surface material is chromium molybdenum vanadium steel welded cobalt chromium tungsten alloy,working pressure is 10MPa~17MPa,valve body material is chromium molybdenum vanadium steel high temperature and high pressure power station gate valve.
1.Designed and manufactured according to standards such as JB/T3595,it can be used in conjunction with domestic equipment
2.The valve chamber adopts a pressure self tightening sealing structure with good sealing performance,and the two ends of the branch pipe are welded structures.
3.The sealing surface of the gate and valve seat is made of Stellite cobalt based hard alloy welded,which has good wear resistance,high temperature resistance,corrosion resistance,and abrasion resistance.
4.The valve stem has undergone quenching and surface nitriding treatment,providing excellent corrosion resistance and abrasion resistance.
5.The structure of the opening and closing components can be designed in different forms such as single board,double board,parallel double board,etc.according to user requirements.
