This is a valve that will not reduce the pressure with the fluid once it's fully opened from naryking's blog

Among the two most typical types of rotary valves will be the ball valves and butterfly valves. Both vales possess a 90 degree turn and therefore are mainly utilized to control the flow of gases and liquids more infor . There are certain features that make the ball valves much better than the butterfly valves.

For a start, a ball valve can provide you with the perfect seal. You will not expect any leakages if your valve is fully closed. The other amazing thing regarding the ball valve is always that it turns regardless of pressure on the supply pipe. This is a valve that won't reduce the pressure on the fluid once it's fully opened.

Trunnion Mounted Ball Valve – A trunnion mounted ball valve has additional mechanical anchoring at the summit and bottom on the golf ball. This special mounting works for larger and better pressure valves. Moreover, this design enables reduction in valve torque because the ball is supported by 50 percent places. Every CAMERON T31 ball valve is trunnion mounted. The trunnion mounted stem absorbs the thrust from your line pressure, preventing excess friction between 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 merely to the stem. This sometimes causes the ball to float slightly downstream. However, during these moments, the ball presses resistant to the seat, building a positive seal.

Rising Stem Ball Valve– A rising stem ball valve incorporates tilt-and-turn operation, eliminating seal rubbing which can be one in the primary reasons behind 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 plus the flow passes uniformly throughout the core face. The Cameron ORBIT rising stem ball valve utilizes this operating principle, delivering fast, low-torque operation and extended reliable performance. Additionally, the valve has the capacity to eliminate localized high- velocity flow that typically creates uneven seat wear exhibited by ordinary ball, gate, and plug valves.

V-ball valves come with a quarter turn (90°) ball rotation, permitting them to operate and turned off at better working pressures ball valve . Because of this, smaller lower torque actuators may be used, which leads to cost savings and efficiency inside the user’s application.

W.E. Anderson’s V-port ball valves are already designed to offer maximum flow characteristics which are substantially greater than similarly sized control valves, as well as offering an inferior size, lighter weight, reduce cost. The NPT Stainless Steel V-Ball Valve, Series WE06, and Flanged Stainless Steel V-Ball Valve, Series WE07, provide the market highly accurate flow control inside a compact ball valve package.
