Floating hard seal ball valve wholesale

The floating metal hard seal Ball valve is suitable for temperatures ranging from -46 to 450 ℃. The floating metal hard seal ball valve seat is a metal hard seal structure, which has the characteristics of high temperature and wear resistance after hardening treatment, and is suitable for working conditions with high temperature or granular media.

Working principle of Floating hard seal ball valve

Opening process: The valve stem drives the ball to rotate 90 °, aligning the ball channel with the pipeline and allowing the medium to flow.

Closing process: The sphere rotates to the cut-off position, and the medium pressure pushes the sphere to move towards the outlet side valve seat, causing the metal sealing surface to tightly adhere and blocking the flow of the medium.

Sealing mechanism of floating hard seal ball valve:

The medium pressure provides the initial sealing pressure to ensure tight contact between the metal surfaces.

The ball float compensates for the wear of the sealing surface and can maintain its sealing performance even after long-term use.
