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.
Description:
Brief introduction:
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.

with rising of pressure of the middle cavity, Small Resistance ball valve has the smallest resistance of all
