Feature:
- 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.
