What's the difference between ball valves and plug valves?by Jeremy Liang SEO specialist When used for cutting off, plug valves have a slightly better regulating ability than sanitary ball valves. But the advantages are limited because although the sealing surface of plug valves is far bigger than that of ball valves and the sealing effect is great, it also causes disadvantages like too much torque and inflexibility. The caliber of regular positive plug structure can’t be made too big due to the influence of the weight of the plug itself.
When used for regulating, the two are similar. Proper holes can be pierced into the rotating body of them to regulate.
Thus, usually plug valves are used on occasions where there’s a high requirement for sealing. But they have smaller calibers. Ball valves can be used on more and wider industrial occasions.
