Fully Welded Floating Ball Valve For Underground Installation Minimum Flow Resistance

Fully Welded Floating Ball Valve For Underground Installation Minimum Flow Resistance

Floating Ball Valve Technical Specifications

Product Description:

The fully-weled ball valve adopts forged material , welded body, instead of bolts and nuts,to aviod any potential leakage from body.

The forged body with regular structure and even thickness can avoid shrinkage cavities, pin holes, cracks, sand holes and other defects occurring to casted valves.

Technical Specifications

(Odorized) containing 0.5% CO2 by volume.

API 6D Certificate

Description:

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.

- 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.
