- Trunnion Mounted 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 and higher pressure valves. Moreover, this design allows for reduction in valve torque as the ball is supported in two places. 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.
- Floating Ball Valve– A floating ball valve is not held in place by a trunnion, and instead is attached only to the stem. This sometimes causes the ball to float slightly downstream. However, when this happens, the ball presses against the seat, creating a positive seal.
- Rising Stem Ball Valve– A rising stem ball valve incorporates tilt-and-turn operation, eliminating seal rubbing which is one of the primary causes of valve failure. When the valve is closed, the core is wedged against the seat, ensuring positive shutoff. When the valve is open, the core tilts away from the seal and the flow passes uniformly around the core face. The Cameron ORBIT rising stem ball valve utilizes this operating principle, delivering fast, low-torque operation and long term reliable performance. Additionally, the valve is able to eliminate localized high- velocity flow that typically creates uneven seat wear exhibited by ordinary ball, gate, and plug valves.
