The Meaning and Expression of the Code of Ball Valves
The knowledge provides a complete and detailed model meaning and editing method for
ball valves, which includes the detailed introduction of the class code of ball valves, the driving method code, the connection form code, the structural type code, the seat material quality code of ball valves, the pressure rating code, the material code of the
valve body, and the form code of flange sealing surfaces.
The main characteristics of stainless steel ball valves are their compact structure, easy operation and maintenance. Different types of ball valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil products, liquid metals, and radioactive media. The valve body of a ball valve can be integral or modular. This type of valve should generally be installed horizontally in pipelines.
Classifications of ball valves:
1. Stainless steel pneumatic ball valves, stainless steel electric ball valves, and stainless steel manual ball valves. The material of stainless steel ball valves is divided into 304,316 and 321 stainless steel ball valves.
2. Stainless steel ball valves rotate the valve core to make the valve unobstructed or blocked. The switch of ball valves is lightweight, small in size, and can be made into a large diameter, with reliable sealing, simple structure, and convenient maintenance. The sealing surface and spherical surface are often in a closed state. They are not easily eroded by the media. It has been widely used in various industries. Only its closing part is a ball, which rotates around the centerline of the valve body to achieve opening and closing.
