What is a ball valve?

In this article, we will introduce the design and operation of the ball valve.

Ball valves are one of the most popular valves on the market, and all ball valves operate in the same way: the ball opens and closes, allowing flow through the valve.

Seal

One of the most important factors in designing a ball valve is dimensional control of all metal parts, surface finish and tolerances between each other. The ball must be perfectly round and preset to fit soft Teflon materials, or harder seats such as reinforced PTFE, peep or metal.

The secret of any seal design is local deformation (ie the yield of the seat produced at the point of contact) and filling the gap between the metal ball and the soft seat. Without such local yielding, bubble or vacuum properties cannot be obtained.
