The stainless steel national standard flanged ball valve is a valve that is very suitable for opening and closing. The opening and closing operation only needs to be rotated 90 degrees and a small torque can be completed. Of course, the current stainless steel national standard flanged ball valve is also suitable for throttling and flow control. It 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. This is also due to the fact that the valve body cavity of the stainless steel national standard flanged ball valve is equal, which can provide a straight, low-resistance flow channel for the medium.
