Floating ball valve and fixed ball valve What is the difference?

Floating ball valve ball is floating, under the media pressure, the ball can produce a certain displacement and squeeze the seal on the outlet end, to ensure that the outlet end of the seal, is a one-sided mandatory seal. Fixed ball valve ball is fixed, does not produce any movement after compression, therefore, in the design of the two seals should have enough pre-tightening force to ensure that the seal is a double-sided forced seal. Usually with the ball in one of the upper and lower stem mounted with thrust or sliding bearings. Floating ball valve design should focus on whether the seal material can withstand the sphere of media load. Because the ball to withstand the load of the working medium all passed to the export seal, therefore, this floating ball structure is widely used in low pressure ball valve. In addition, the design should also consider the large-diameter ball valve operation requires a larger torque.
