Floating Ball Valve

Blow-out Proof Stem

Stem is designed with collar, which will prevent stem from being blown out, when medium passes through the valve or the valve is disassembled to repair. (Fig.1)

Anti-static Device

When open and close the valve, the friction between the ball and the non-metal seat will produce static charges. To avoid static sparkle, an antistatic device is designed on the valve to derive the accumulated static from the ball. (Fig.2)

Fire Safe Design

The seat, steam and body joint of ball valve are with fire safe design. When non-metal materials such as O-rings, soft seat etc. are decomposed or deteriorated by fire, ball valve changes to metal to metal auxiliar seal structure, which will prevent/control effectively internal leakage or external leakage.
