Details

We provide various metal seated balls to match the seat which made by clients themselves. All of the metal seated balls finished with perfect roundness. Even more, the last special process after grinding will make the surface as mirror, just like polishing effect. The excellent roughness will make your ball valve longer service life, and less torque. As the expert of metal seated ball, we believe that we can change the valve and make the ball valve better.
