Casting Steel B.B Globe Valve

Cast steel B.B cut-off valve, also known as cut-off valve, is a forced-sealed valve, so when the valve is closed, pressure must be applied to the valve flap to force the sealing surface to not leak. The movement of the valve stem is a lifting rotary lever type that can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media.
