Trunnion Mounted Floating Ball Valve With Reliable PTFE Seal
Structure
Floating Ball Valve Description:
The ball valve is designed and manufactured according well to API
608. Floating ball when small caliber,
and fixed ball when large caliber.
It has fire protection structure and antistatic device. Widely used
for petroleum, chemistry, water
treatment industries.

Floating Ball Valve Feature:
- Reliable Seal Structure
The seat is made of PTFE. Because the contact area between seat and
the ball will
becomes more high with rising of pressure of the middle cavity,
Small Resistance ball valve has the smallest resistance of all the
valve, in the case
of reduced bore, the resistance is little still.
- Prompt switch
The ball valve circumrotates in 90°,It work quickly to open or
close.
