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¡ã,It work quickly to open or close.
