Design and Manufacturing Specification

Material Selection

Feature

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

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 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.

Wrench with Valve Open/Close Indication

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 Gear Operated 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.
