F91 F92 Forged steel gate valve Product introduction
F91 F92 Forged steel gate valve manufacturer, factory and supplier. F91 F92 Forged steel gate valve is used for high pressure and high temperature steam system, F91 F92 Forged steel gate valve is uniquely designed for demanding conditions in sectors of power plant, refinery, oil & gas ,etc. F91 F92 Forged steel gate valve has superior ruggedness and assured longevity under maximum pressure rating of CL4500 and working temperature of 600 °C.
F91 F92 Forged steel gate valve feature:
- F91 F92 Gate valve of high temperature and high pressure for power station adopt advanced flow channel and other straight-through structure, which greatly reduces the flow resistance coefficient and energy loss, and significantly improves the service life and performance of the valve.
- The middle cavity of the valve adopts a pressure self-tightening sealing structure with good sealing performance. Both ends of the branch pipe are welded structures.
- The sealing surface of the valve plate and the valve seat is made of stellite cobalt-based hard alloy surfacing, which has good wear resistance, high temperature resistance, corrosion resistance and scratch resistance.
- After quenching and tempering and surface nitriding, the valve stem has good corrosion resistance and scratch resistance.
- The structure of the opening and closing parts can be designed into single wedge, double wedge, parallel double wedge and other forms according to user requirements.
