Three Way Ball Valve
Y-type three-way ball valve is mainly used to change the medium flow direction in Y-type pipeline, so that two of them are connected or cut off to play the role of reversing. The three channels of the valve body are designed to form an angle of 120 ° or 135 ° between the two through holes. Its flow channel is flat, the fluid resistance is small, the flow capacity is strong, and the switching is easy

Ball valve and plug valve belong to the same type of valve. Only its closing part is a ball. The ball rotates around the center line of the valve body to open and close. Ball valve is mainly used to cut off, distribute and change the flow direction of medium in the pipeline. Ball valve is a new type of valve widely used in recent years Main performance specifications |
