| Features：
Ball Valve is an important valve in the category of the petrochemical industry, long pipeline, and other fields are widely used. Ball Valve pieces of the closure is a hole the ball (or part of the ball), with the ball stem rotating, the valve open or closed. In various valve, the valve in the flow of least resistance, the entire trail valve opened, Ball channel, Valve Corridor and the connecting pipe diameter and into an equivalent diameter, the medium is almost no loss of flow. Ball valves can be rotated 90 ° All-Full accomplished quickly. With the same specifications valve, the valve closing, the valve small size, light weight, ease of installation of pipelines.
