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.
