Among the two most popular types of rotary valves include the ball valves and butterfly valves. Both vales employ a 90 degree turn and they are mainly accustomed to control the flow of gases and liquids more infor . There are certain features which can make the ball valves much better than the butterfly valves.

For a start, a ball valve supply you with the perfect seal. You will not expect any leakages in the event the valve is fully closed. The other amazing thing regarding the ball valve is always that it turns regardless of pressure through the supply pipe. This is a valve that will not reduce the pressure on the fluid once it can be fully opened.

Trunnion Mounted Ball Valve – A trunnion mounted ball valve has additional mechanical anchoring at the summit and bottom on your ball. This special mounting works for larger greater pressure valves. Moreover, this design makes for reduction in valve torque because the ball is supported into two places. Every CAMERON T31 ball valve is trunnion mounted. The trunnion mounted stem absorbs the thrust in the line pressure, preventing excess friction relating to the ball and seats, so even at full rated working pressure operating torque remains low.

Floating Ball Valve– A floating ball valve isn't held in place by the trunnion, and instead is attached simply to the stem. This sometimes causes the ball to float slightly downstream. However, during these moments, the ball presses resistant to the seat, setting up a positive seal.

Rising Stem Ball Valve– A rising stem ball valve incorporates tilt-and-turn operation, eliminating seal rubbing that is one in the primary reasons for valve failure. When the valve is closed, the core is wedged resistant to the seat, ensuring positive shutoff. When the valve is open, the core tilts away in the seal and also the flow passes uniformly round the core face. The Cameron ORBIT rising stem ball valve utilizes this operating principle, delivering fast, low-torque operation and long lasting reliable performance. Additionally, the valve will be able to eliminate localized high- velocity flow that typically creates uneven seat wear exhibited by ordinary ball, gate, and plug valves.

V-ball valves use a quarter turn (90°) ball rotation, letting them operate and turn off at higher working pressures ball valve . Because of this, smaller lower torque actuators works extremely well, which ends up in cost savings and better efficiency within the user’s application.

W.E. Anderson’s V-port ball valves have already been designed to offer maximum flow characteristics that happen to be substantially more than similarly sized control valves, as well as offering a reduced size, lighter weight, reducing cost. The NPT Stainless Steel V-Ball Valve, Series WE06, and Flanged Stainless Steel V-Ball Valve, Series WE07, provde the market highly accurate flow control within a compact ball valve package.
