Main Products: gate valve ball valve check valve globe valve control valve |
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 chemistrywater treatment industries.
-Anti-blowout Structure of Valve Stem
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 90o,It work quickly to open or close.
