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.

Manual Y Type Globe Valve

Y-type globe valve is the most widely used valve, it is popular because of the small friction between the sealing surface in the process of opening and closing, more durable, opening height is not large, easy to manufacture, convenient maintenance, not only suitable for low and medium pressure, but also suitable for high pressure. Its closing principle is to rely on the pressure of the valve lever, so that the sealing surface of the valve disc and the sealing surface of the valve seat are closely fitted to prevent the circulation of the medium.

Manual Pressure Sealing Globe Valve

Forged steel self-sealing globe valves are valves in which the closing member (disc) moves along the center line of the seat. According to this form of movement of the valve disc, the change of the valve seat orifice is proportional to the valve disc stroke. Because the valve stem opening or closing stroke is relatively short, and has a very reliable cut-off function.

Manual Female Threaded and Socket Welded Globe Valve

Forged steel socket weld stop valves come in three bonnet designs. The first is bolt type valve cover, according to the design of the valve, the valve body and the valve cover with bolts and nuts connected, winding gasket (316 wafer flexible graphite manufacturing) seal. The second design form is welded valve cover, according to this design form of valve, the valve body and the valve cover with thread connection, welding seal. The third is the self-sealing valve cover, according to this design form of the valve, the valve body and the valve cover with thread connection, internal pressure self-sealing ring.
