What is a V-Port Ball Valve?

A V-Port Ball Valve is a specialized ball valve with a V-shaped opening in the ball or seat. As the valve opens or closes, the v-notch gradually increases the flow area, enabling fine-tuned throttling and linear flow characteristics—something standard ball valves can’t provide. Available in 15°, 30°, 60°, or 90° V-notch profiles depending on flow control needs

Key Features of V-Port Ball Valves

Accurate flow control for throttling and modulating service

V-Port vs Standard Ball Valve – What’s the Difference?

Feature	V-Port Ball Valve	Standard Ball Valve
Flow Control	Precise throttling	Not suitable for modulating
Flow Curve	Linear / Equal %	On/Off only
Actuation	Positioner-ready	On/Off actuator
Seat Wear	Better distributed	May damage seats on throttling
Cost	(Higher precision)	(General use)

Maintenance & Handling Tips

Install with clear actuator access
Use a control valve with feedback loop for flow adjustment
Periodically test actuator and positioner calibration
Use filters upstream to avoid media buildup in the V-notch
Flush clean after each cycle if used with paints or adhesive

FAQs

Can I use a V-port valve for on/off only?

Yes—but it’s designed for throttling. For basic shut-off, use standard ball valves.

What’s the ideal V-angle for flow control?

15° = ultra-precise, low flow
30° = accurate control for mid-flow
60° = general-purpose flow regulation

Paint, ink, chemical, water treatment
Pharma formulation
Food blending
Oil injection control
