Produc , t Characteristics

A. Small fluid resistance

Low fluid resistance. The fluid resistance of the ball valve is the smallest of
all valves, even for shrink ball valves.

B. Good sealing

Good sealed seat. The sealing ring made of elastic materials such as PTFE is
easy to seal, and the sealing capacity of the ball valve increases with the
medium pressure.

C. Good self-lubrication

Because the PTFE has good self-lubrication characteristics, the friction loss
with the ball valve is small, and the service life of the ball valve is long.



Advantages of a Flange Ball Valve

A. High-level platform design that meets the ISO5211 standards

The drive installation platform, designed according to ISO5211 standards, can
directly install all kinds of drives, and have two sets of PCD for customers to
choose from

B. Subinking cover design

This cover is designed to prevent leakage of the valve stem and the valve body
without removing the drive device for on-site use.

C. Design of double-layer butterfly-shaped shrapnel device

Two butterfly-shaped shrapnel prepressed in advance will compensate for the
microleakage of the valve stem, releasing the deformation of the ride
prepressed and pressing the fill again.

D. Third heavy seal design of valve stem "O" type ring

When the stem turns, the "O" ring can reduce the direct friction of the stem to
the valve body, and can assist the stem part at the low pressure. If the pipe
medium is gas, the "O" ring is better sealed than the PTEE.

E. explosion-proof design of valve stem

The structural design of the stem and body can prevent the stem from rushing
from the body due to excessive pressure in the chamber.

F. Design of the sealing lines

A concentric positioning seal structure between the valve body and the valve
cover can prevent leakage of excess material and movement when the sealing line
extrusion.

G. Anti-static electricity design

Through the static contact of the spring behind the ball, the ball body
friction to the valve stem.

I. fire protection planning

When a fire occurs on site, the valve seat is burned or vaporized under the
influence of high temperature.
