4" ~ 42 " Dynamic Balance Cast Steel Gate Valve Full Bore Manual Operation

1 .  Valve seat adopts the structure of O-ring seals and pretightening float valve seat, the soft

sealing inlays fluoroplastic, it provides the function of double sealing: fluoroplastic to metal and

metal to metal. And at the same time, the fluoroplastic can remove the dirt of the gate disk.

2 .  Of the metal to metal sealing, there is a grease injection structure outside the valve, grease

injects the sealing part through the seat, in this way achieves the aim of zero leakage.

3 . Through conduit gate valve always coincide with the sealing surface,whether the disc is full

open-or fullclosd; sealing surface to be protected from scouring by media dilectly, thereby extending

the service life. In fulltime, smooth channel for the direct and flow resistance coefficient is extremely

small, no pressure loss, leading to Pig.
