Structural features:

No valve cover, integral forging structure, meeting high pressure and high temperature requirements, using needle roller bearings with external valve stem threads, the opening and closing valve stem does not rotate, preventing the packing from being twisted and damaged, and reducing operating torque; The valve stem has an upper sealing structure, and the sealing surface is welded with hard alloy, which has a long service life. It can be used in critical and harsh environments worldwide, including high-pressure drop, steam emissions, steam injection, rapid isolation, 6000PSI (414bar) high-pressure gas, and 593 ° C ultra-high pressure steam.
