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.
