Y-shaped integrated globe valve
Text description:
Structural features:
No valve cover, integral forging structure, meeting high pressure and high temperature requirements, using needle roller bearings with external valve stem threads, opening and closing the valve stem without rotation, preventing torsional damage to the packing 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 situations around the world, including high-pressure drop, steam discharge, steam injection, rapid isolation, 6000PSI (414bar) high-pressure gas, and 593 ° C ultra-high pressure steam.
