When the valve is turned on, the perforation aligns with the pipeline's outlet to allow liquids, slurries, gases and other medium to flow through it. When it is turned off, the ball turns and seals off the flow. The mechanism is simple, which is why ball valves can withstand the flow of extreme temperature, volume, and pressure.
The advantages of ball valves outweigh the disadvantages that are very few when compared to other valve types. Ball valve manufacturers do not recommend ball valves for applications with a heavy, sludgy medium like slurries. They are also not recommended for sustained throttling.
Our post explores all the advantages of using ball valves to help users make a wise choice for their applications.
