Positive Flow High Temperature And High Pressure Manual Globe Valve

The positive flow high temperature and high pressure manual globe valve designed by Dazhong Valve Group, the valve body and valve cover are made of die forgings, and are connected with threads and fixed with set screws. The structure is simple and the maintenance is convenient. The valve seat is welded on the valve body, and the surface is sealed. The valve stem is made of helium-infiltrated steel, and the valve seat and valve disc sealing surface are all made of cobalt-based cemented carbide plasma spray welding, which has high hardness, scratch resistance and good sealing performance.

• Installed on high-pressure water and steam pipelines, used as an opening and closing device, the valve must be in a fully open or fully closed state, and cannot be used as a regulating valve.
