Brief Introduction

Electric Actuated ball valve is an O-type fixed ball valve designed with an upper and lower stem fixed valve core (shaft supported) and a movable sealing seat. More stable work. Equipped with automatic compensation function, bi-directional sealed valve seats have great shear force and self-cleaning function when rotating without gap between them.

For the full bore valve, the bore diameter i.e hole in the ball has the same internal diameter as the pipe, whereas a reduced bore valve has a smaller bore diameter than the internal diameter of the pipework it is on.

Full-port ball valves are used where their low flow resistance is of value such as on pump suction pipes, where a pressure drop can affect pump performance. They are also used in flows containing mixed liquids and solids where flow restrictions can cause separations in the materials causing buildups and thus reducing the flow in the pipes.  

Product Feature.

1. The shear force between the ball and the metal seat type V incision, especially suitable for containing fiber and small solid particle, pulp and other medium.
2. Fully open flow capacity, small pressure loss, and the media will not deposit in the body cavity.
3. Using a spring-loaded movable seat structure , Preventing the occurrence of ball core and valve seat from jamming or other issues, reliable sealing and long service life.
4. The valve has the advantages of accurate regulation and reliable positioning function, approximately equal percentage flow characteristics, large adjustable range, the maximum adjustable ratio 100:1.

Main Parameters.

Nominal diameter DN, Rated flow coefficient Kv, Allowable pressure difference.
