What's the difference between floating ball valve and fixed ball valve?
The ball ceramic valve evolved from the plug valve, in which
there is a plug initially. The ball valves also can be divided into
floating ball valve and fixed ball valve. The differences between
floating ball valve and fixed ball valve are as follows. For the
fixed ball valve, the ball is fixed and will not move even under
pressure. There are floating valve seat to press the sing real
tightly on the ball when suffering the media's pressure. Besides,
the axletree is equipped with the stem connecting with the ball.
The floating ball valve contains the ball floating inside. The
structure is simple and has good tightness. When the media goes
through, the pressure is passed into the seal rings, therefore the
material of the seat rings should be well considered in design.
