Vee-Notch Ball Control Valve Solutions

Chemoil Advance Technology supplies Vee Notch Ball Control Valves from recognized manufacturers for precise flow regulation and automated process control in demanding industrial applications. The Vee-notch ball design provides a controlled flow characteristic, making this type of valve suitable for applications where accurate and responsive modulation of process media is required.

The valve uses a V-shaped or V-notch opening in the ball to control the available flow area as the ball rotates. This design allows the valve to provide more controlled flow adjustment than a conventional full-port ball valve in suitable modulating applications. The configuration can be selected according to the required flow capacity, pressure conditions, process medium and control requirements.
