Trunnion Mounted Ball: The trunnion mounted ball valve is a quarter turn valve which uses a rotating ball with a hole through it, which can be aligned with the flow path (open position) allowing flow and blocks flow when the ball is rotated by 90 degrees. A trunnion mounted ball has mechanical anchoring at the top and bottom, which is suitable for larger and higher pressure valves. Ball valves are used for on/off and throttling services.


Trunnion mounted ball valve is an economical and high-performance quarter-turn valve. The quarter-turn operation is fast and reliable which makes this valve applicable to quick on-off operation and tight seal. This ball valve is widely used in pulp paper refinery, mining, chemical fiber, sewage and water treatment, sugar refining industry.
Separate body design, various materials are available.
The ball is trunnion mounted, which prevent seat damage and reduce seat ware dramatically comparing with floating ball valve.
The ball is precisely machined and mirror finished for bubble-tight shutoff and less operating torque.
Full bore design minimizes the flow resistance and achieve better valve performance.
With seats on both sides,the trunnion ball valve can handle flow in either direction with 0 leakage.
Seat is spring preloaded, which ensures self sealing adjustment when flow pressure changes to achieve 0 leakage.



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.
