Manual Flange and Butt Welded Globe Valve

Manual flange butt welding stop valve is mainly used to cut off or control the flow of fluid in fluid pipeline. It combines the characteristics of manual flange stop valve and butt welding stop valve, and is suitable for fluid control in medium and small caliber, medium and low pressure, normal temperature and high pressure and high temperature environment. Valve body and bonnet are usually made by casting or forging process, which has good strength and tightness. The valve seat and valve core are made of stainless steel and other materials, which have strong corrosion resistance and can meet the control requirements of various fluids.
