Feature
Floating Ball Valve Blow Out Proof Stem Construction
The lower end of stem is terraced and installed from inside of the valve body. This construction
insures a blow out proof stem and metal to metal seal in case of fire.
Anti-static Design
During operating, The special antistatic device can discharge the static electricity accumulated
on the ball while the valve is opening and closing.
Middle Flange with No Leakage Design
Floating Ball Valve's Body and Cap connection are sealed by gaskets. To prevent leakage from fire, high
temperature or vibrations, metal to metal sealing between the body and cap is good effect.
Locking Device
The Floating Ball Valve is equipped with locking holes for the lever in the full open and full closed position to
prevent accidental while opening and closing.
Fire-Safe Design:API607/API6FA
Each possible leaking part between Ball and Body, Middle flange, Stem and body is designed for
metal to metal contaction which conforms to the fire-proof requirements of API 6FA and API 607.
In case of extreme fire-proof conditions, the packing and gasket material made of flexible graphite
can insure zero leakage.

When the handle(lever) is on the same horizontal line with the pipe, this indicates the valve is
open. When the handle(lever)is on the vertical line with the pipe, this indicates the valve is closed.
Advanced and Exclusive Seat Design
With many years of Ball Valve manufacturing experience and advanced technology from abroad,
the cone sealing surface developed, makes the more reliable sealing. Our designs are available
with various types of seat materials can offer low friction and low operational torque.
