As long as the ball valve is rotated by 90 degrees, the rotating torque can achieve the effect of tight sealing. In recent years, the development between balls has changed from cut-off and cut-off to throttling and flow control. It is widely used in oil and gas pipelines, oil refining pumping devices and nuclear industry. With the development of economy, in the field of large and medium caliber, medium and low pressure, ball room will also be the leading product to be applied. The patent number of this product: ZL201320812145. Product features  (1) The ball valve is simple in structure, small in source strength, and the ball trickle resistance of the full diameter is basically zero.  (2) It has t…
