FAQs (Frequently asked questions)
Find detailed answers to common questions about V-Notch Ball Valve (Segmented V-Port) in our Knowledge centre.
A V Notch Ball Valve (also called a V Port Ball Valve or Segmented Ball Valve) is a type of quarter-turn control valve where the ball features a “V” shaped cut instead of a standard round hole.
This unique V-profile creates a precise opening that allows for accurate throttling and flow regulation, similar to a globe valve but with higher flow capacity. The sharp edge of the V-notch also provides a shearing Effect, enabling the valve to cut through fibers and solids without clogging, making it ideal for paper pulp, slurries, and viscous fluids.
While both are quarter-turn valves, a V-Notch ball valve which has V-shaped opening offers precise throttling (flow control). Standard ball valves are typically on/off valves and can trap debris, waste etc, whereas V-Notch designs provide a self-cleaning effect.
Wafer type V notch ball valves are lighter, more compact, and cost-effective, fits between two pipe flanges. Flanged versions are more robust and easier to install/remove without disturbing the pipe alignment.
