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 Features:
- 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.
