DESIGN & MANUFACTURE CONFORM WITH:
|Materials of parts|
1~12 Trim material
Flexible graphite+304/Flexible graphite+316
|*Materials could be choosed according to customers' requirement & working condition.|
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.
