Trunnion Mounted Ball ValvesTrunnion Mounted Ball Valves

Trunnion mounted ball valve usually has floating valve seat, under the media pressure, the valve moves, so that the sealing ring tightly pressed on the ball in order to ensure the seal. Usually in the upper and lower shaft there are bearings, operating torque is small, suitable for high pressure and large diameter of the valve. In order to reduce the valve operating torque and increase the reliability of the seal, valve seal has emerged in recent years, both the pressure injection of a special lubricant in the sealing surface, to form a layer of film that enhances the sealing, and reduce operating torque, more suitable for large-diameter high-pressure valve.

trunnion mounted ball valve is suitable for Class150 to Class2500 P N ~ C, 16 ~ P N 160, JIS 10K to JIS 20K of the pipeline, used to cut off or connect the line of medium, use different materials, can be separately applied to water, steam, oil, liquefied petroleum gas, natural gas, coal gas, nitric acid, acetic acid, oxidizing medium, urea and other media. Fixed ball valve can be driven by worm gear transmission, manual, pneumatic or electric. Fixed ball valve use flange connection, can also adopt the butt welding.
