Product advantages
Strengthen the seal and improve the reliability of the seal.Self-cleaning structure of the sealing surface. When the sphere is tilted away from the valve seat, the fluid in the pipeline will pass through the sealing surface of the sphere uniformly at 360 °. It not only eliminates the high-speed fluid from locally scouring the valve seat, but also removes the accumulation on the sealing surface to achieve the purpose of self-cleaning.
