First we need to understand what a stainless steel ball valve is:
The stainless steel ball valve only needs to be closed with a 90 degree rotation and a small turning torque. The fully equal valve body cavity provides a small, straight-through flow path for the medium. The main features of the ball valve are its compact structure, easy operation and maintenance, suitable for general working media such as water, solvent, acid and natural gas, and also suitable for medium with harsh working conditions such as oxygen peroxide, methane and ethylene. The ball valve body may be integral or combined. This type of valve should generally be installed horizontally in the pipeline. Stainless steel ball valve classification: stainless steel pneumatic ball valve, stainless steel electric ball valve, stainless steel manual ball valve. Stainless steel ball valve material is divided into 304, 316, 321 stainless steel ball valves.
How to identify the quality of stainless steel ball valves:
1. Compare the depth of the scratches of the two materials
2. The density of the material is related to the amount of other substances during quenching.
3, due to the relationship between material density can be distinguished
4, the density of large scratches is shallow and the opposite is deep
5, can also be based on the material of stainless steel to distinguish if you still do not understand can also go to this query:
