Ball ball valve is used with a circular channels as opening and closing, the sphere with the valve rod rotation realize on-off movement.ball valve is rotated 90 degrees, the cock body for a sphere, a round hole or tunnel through its axis.Ball valve in the line is mainly used for cutting, distribution, and change the flow direction of medium, it just has to rotate 90 degrees of operating and small rotational torque can be closed tightly.
 Pipeline ball valve classification and USES
Ball valve can be divided into: floating ball ball valve and the fixed ball ball valve, V type ball valve, sulfur discharge ball valve, ball valve, plastic ball valve, card sets of ball valves, welding ball valve, air valve, one-piece ball valve, chip ball valves, threaded ball valve, through ball valve, three-way ball valve, four-way valves, insulation ball valve, ball valve, pipeline ball valve, rail cant ball valve, anti-corrosion ball valve, etc.
 Pipeline ball valve classification and USES
