A V port ball valve has the 'v' shaped ball or even a 'v' shaped seat. This allows for linear and in some cases equal percentage flow characteristics. When the valve is with the closed position and opening is commenced small end on the 'v' is opened first allowing stable flow control in this stage view this site . This type of design takes a generally better quality construction on account of higher velocities on the fluids, that may damage a normal valve. When machined correctly these are typically excellent control valves, offering superior leakage performance.
Many industries encounter downside to residues inside the ball valve. Where the fluid was created for human consumption, residues can also be health hazard, when where the fluid changes every so often contamination of a single fluid with another may occur. Residues arise because from the half open position on the ball valve a gap is produced between the ball bore and the body by which fluid may be trapped. To avoid the fluid stepping into this cavity, the cavity needs to be plugged, which might be done by extending the seats in this particular manner that it's always in exposure to the ball. This type of ball valve is referred to as Cavity Filler Ball Valve.
When you'll need precise control of your application, a globe valve is often more accurate over a ball valve. Globe valves are the industry standard for control valves because they're good at regulating flow, whereas ball valves are better for on/off control without pressure drop.
V-Port Ball ValveIf you will need to use a ball valve to manage your process, you should consider different kinds of ball valves depending on the application for more . A trunnion or v-port ball valve will do better and enable for more accurate adjustability using scenarios.
Trunnion ball valves come with an additional mechanical anchoring in the ball at the summit and bottom. They utilize a splined or keyed stem connection that eliminates any play between your ball and stem. V-port ball valves employ a ‘V’ shaped ball instead from the standard round hole. This allows for much more control because from the tapered opening, allowing for additional linear flow.
In-Line Repair. You can repair 3-piece valves without complete removal in the line, unlike 1- and 2-piece ball valves. Simply remove three with the four cap screws on them, and the body swings out for replacement on the seats and seals.
Protected Seat. The Tri-Pro Series valves also boast a protected seat and encapsulated body seal design. This isolates and protects the seats and seals in the flow path, preventing cold flow and allowing long-term performance in demanding applications.
