CSV  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.
