WebThe trunnion ball valve is an essential device for regulating the flow of fluids- steam, gas, or oil in pipeline. It is quarter-turn designs with a ball capable of rotating 90 degrees on its axis to either block or allow the flow of fluid. These valves have a spherical disk design at the center, which rotates to regulate the start-stop flow cycle. WebMar 3, 2011 · however, minimum length of anchorages shall be 2/3 of radius of gate. when trunnion is kept 1/3 height of gate, anchor girder is kept in horizontal position. if trunnion is kept above 1/3 height of gate, anchor girder is kept inclined at an angle “θ”, so as to keep them parallel in direction of resultant load passing through trunnion. 54.
