Now there are increasingly brands and categories of pneumatic ball valves in the market, and the quality is patchy. As a buyer, how can you distinguish
the quality of pneumatic ball valves?
First of all, pay attention to the appearance of
the pneumatic ball valve to see if there are any defects like bubbles and burrs. Make sure whether the valve pricks your hands or not and then check if the inside of the valve is clean and has sand holes. Also, measure the wall thickness of the valve to see if it meets the national standard, so as to prevent some manufacturers from cutting corners and offering unqualified pneumatic ball valves.
Secondly, know if the manufacturer has advanced assembly and high-quality technical guidance. If necessary, you can also test the material of the ball valve to see if it is unqualified, so as to prevent the material from being unqualified or even rusty. Besides, you can check the valve core, an important part of the valve. It directly determines the performance and service life of the pneumatic ball valve. High-quality pneumatic ball valves are usually made of metal materials with high hardness and high wear resistance, and have strict requirements on machining accuracy to ensure that the ball valves can work stably under high pressure.
Finally, as a good pneumatic ball valve, it has extremely high requirements on the smoothness, roundness and concentricity of the valve body. The seal oil tank should be smooth and well-rounded.
