Floating
Ball Valve
The floating ball valve is a kind of
commonly used valve. It is named due to the fact that the ball and stem pass
through the axis of flow channel. The Floating ball valves include low platform
type and high platform type.
The low platform type products are suitable
for manual operation and electric or pneumatic actuator can also be additionally
installed if necessary. For the high platform type products, the electric or
pneumatic actuator can be installed without extra yoke.

Trunnion
Ball Valve
The trunnion ball valve is used for cutting
or connecting the medium in various pipelines of class150-class2500 and pn16-pn320.
It can be suitable for various media such as water, steam, oil, liquefied gas,
natural gas, coal gas, nitric acid, acetic acid, oxidizing media, urea and etc.
It is widely used in such industries as chemical industry, petroleum, natural
gas, metallurgy and etc. The driving modes of the trunnion ball valve include
worm and worm gear driving, manual driving, pneumatic driving and electric
driving. The trunnion ball valves generally adopt flange connection, and butt-welding
connection is also adopted. The seat can be soft seal seat or metal hard seal
seat.
