Specifications
Valve Features
Split body design with flanged ends for fast installation, in-line
maintenance and rebuilding. Solid ball construction provides
structural integrity and minimizes flow turbulence.
Body join is designed to prevent excessive compression of valve
internals, resulting in consistent and low operating torque.
Mounting pad complied with ISO 5211 for ease and interchangeability
of actuation
Bottom-loaded blow-out proof stem.
Investment cast body & cap on sizes 1/2″ to 2″. Sand cast body &
cap on sizes 2-1/2 ” to 10″.
Basic design complied with ASME/ANSI B16.34 & EN 12516-1
Flanged ends complied with ASME/ANSI B16.5
Face-to-face dimensions complied with ASME/ANSI B16.10
Tested according to API 598 & ANSI B 16.34
Size Range:
- DN15~DN200
Pressure Rating:
- GB PN16 PN25 PN40
Temperature Range:
- -20°C~185°C
Ball valve and gate valve are the same type of valve. The
difference is that the opening&closing part is a ball, and the
ball rotates around the valve body to achieve the valve
opens&closes. The ball valve is mainly used in the pipeline to
cut, distribute and change the flow direction of the medium. Flange
ball valve standard GB/T21465-2008 "Valve terminology" is defined
as: the opening and closing member (sphere) is driven by the valve
stem and rotates around the axis of the valve stem.

Application
The ball valve is mainly used in the pipeline to cut, distribute
and change the flow direction of the medium.
Strength of Ball Valve
1. Anti-static performance: a spring is arranged between the ball,
the valve stem and the valve body, and the static electricity
generated by the switching process can be derived.
2. Since the material such as polytetrafluoroethylene has good
self-lubricating property and the friction loss with the spherical
body is small, the service life of the pneumatic ball valve is
long.
3. The fluid resistance is low, and the pneumatic ball valve is the
one with the smallest fluid resistance in all kinds of valve.
4. The valve stem seal is reliable. Because the valve stem only
performs the same movement as the lifting movement, the packing
seal of the valve stem is not easy to be damaged, and the sealing
capacity increases as the pressure of the medium increases.
