Abstract
A valve includes a ball coupled to a stem which is turnable by an operator element. The ball is formed with a flow passage and the ball is sealed in a valve seat by means of seals. The stem includes bypass structure, which upon rotation of the stem, is alignable with an upstream diverging tube and with a downstream diverging tube to allow bypass fluid flow from the upstream diverging tube to the downstream diverging tube for balancing a difference in pressure between upstream and downstream portions of the valve.
