About Trunnion Ball Valve
A trunnion mounted ball valve has additional mechanical anchoring at the top and bottom on the ball. This special mounting is suitable for larger size and higher pressure valves. Moreover, this design allows for reduction in valve torque as the ball is supported in two places. Every TEKO trunnion mounted ball valve is trunnion mounted. The trunnion mounted stem absorbs the thrust from the line pressure, preventing excess friction between the ball and seats, so even at full rated working pressure, operating torque remains low.
