FLOATING BALL VALVE FEATURES

VALVE BALL SUPPORTING

The lower end of stem is terraced and is installed
from the inside of the valve body. This
construction insures a blow out proof stem and
metal to metal seal in case of fire.

ANTISTATIC DESIGN

During operation of valve, static electricity may
accumulate on the ball. The special antistatic
device can discharge the static electricity during
opening and closing of the valve.

FIRE-SAFE DESIGN: API607/API6FA

Each possible leaking part between Ball and
Body, Middle flange, Stem and body are
designed for metal to metal contact which
conforms to the fire-proof requirements of API6FA
and API 607. In case of extreme fire-proof
conditions, the packing and gasket material shall
e flexible graphite to insure zero leakage.

LOCKING DEVICE

The valve is equipped with locking holes for the
lever in the full open and full closed position, to
prevent accidental opening and closing of the
valve.

MIDDLE FLANGE WITH

NO LEAKAGE DESIGN

(Body and Cap connection)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 aintained.

WRENCH WITH VALVE

OPEN/CLOSE INDICATION

When the handle(lever) is on the same
horizontal line with the pipe, this indicates the
valve is at open position. When the
handle(lever) is on the vertical line with the pipe,
this indicates the valve is at closed position.

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 sealing more reliable. Our designs
are available with various types of seat
materials that offer low friction and low
operational torque.
