How To Choose Stainless Steel Ball Valve Correctly

3 Piece Threaded Ball Valve Classification: Stainless steel pneumatic ball valve, stainless steel electric ball valve, stainless steel manual ball valve. Stainless steel ball valve materials are divided into 304, 316, 321 stainless steel ball valves. Stainless steel ball valves 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. The ball valve body can be integral or combined. The working principle of the ball valve is to rotate the valve core to make the valve unblocked or blocked. The stainless steel ball valve is light and small in size. It can be made into a large caliber, with reliable sealing, simple structure, and convenient maintenance. The sealing surface and the spherical surface are often in a closed state and are not easily eroded by the medium. It is widely used in various industries.

Basis for selecting stainless steel ball valves

1. The nature of the working medium: working pressure, working temperature, corrosion performance, whether it contains solid particles, whether the medium is toxic, whether it is flammable or explosive, and the viscosity of the medium.

2. The purpose, working conditions and operation control methods of the selected stainless steel ball valve, valve specifications and categories should meet the requirements of the pipeline design documents, and the working pressure should be greater than or equal to the working pressure of the pipeline.

3. Installation size and external dimension requirements: nominal diameter, connection method and connection size with the pipeline, external dimension or weight limit, etc.

4. Additional requirements for the reliability, service life and explosion-proof performance of the stainless steel ball valve.

5. Requirements for the fluid characteristics of the stainless steel ball valve: flow resistance, discharge capacity, flow characteristics, sealing grade, etc.
