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.
