Floating Ball Check Valve Description:
The fully-weled ball valve adopts forged material , welded body,
instead of bolts and nuts,to aviod any potential leakage from body.
The forged body with regular structure and even thickness can avoid
shrinkage cavities, pin holes, cracks, sand holes and other defects
occurring to casted valves.

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.
Features:
- Anti-blowout Structure of Valve Stem
When medium pass through the valve, the pressure in valve body may
possibly push the stem out, or
when the valve is in repair, if there is pressure in the middle
cavity, the stem or medium seems to easily
fly out upon disassembling the valve, which can cause injures to
human beings, To prevent the
possibilities, a dummy club is packing and thrust bearing are burnt
or packing is damaged due to other
causes, the pressure of medium in valve body will make the dummy
club of valve stem in close contact
with the upper seal face of valve body. Thus to prevent medium
leaking out from the damage packing
position.
- 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.
