The working principle of the PPR globe valve and ball valve: the closing principle of the globe valve is to rely on the pressure of the valve rod to make the sealing surface of the valve disc and the sealing surface of the valve seat closely fit to prevent the flow of the medium; the flow direction of the globe valve is all from top to bottom , so there is directionality when installing. The ball valve is a valve whose opening and closing part (ball) is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for fluid regulation and control. There is a strong shear force between the metal valve seats, especially suitable for media containing fibers and tiny solid particles.
