Structural features
1. This valve is a full-bore floating ball valve with compact structure, beautiful appearance and small flow resistance coefficient.
2. The sealing surface is made of fluoroplastic and has self-lubricating function, so it has a long service life.
3. The sphere and F4 seat are tightly sealed, with zero leakage function, and can automatically compensate for the wear error by plastic deformation, so as to achieve good sealing performance and long service life. In order to ensure the sealing at the valve stem, a stuffing box and a gland are added to the valve body for sealing, and no leakage is allowed.
