Description
3PC Floating Ball Valve
Working principle 1、The floating ball valve has only the upper stem of the ball, and the ball can be slightly displaced, so it is called floating ball valve. The fixed ball valve has a fixed shaft at the bottom of the ball, which fixes the position of the ball, so it cannot be displaced, so it is called a fixed ball valve. 2, floating ball valve ball due to the pressure of the medium, the ball displacement, tightly attached to the seat to achieve sealing, the need to consider whether the seat material can withstand the working pressure. The ball of fixed ball valve is fixed, is driven by the pressure of the medium seat movement, tightly on the ball to achieve sealing.
