Segment Ball Valves for High-Performance Process Control
High capacity, high rangeability, and exceptional shear capability for demanding industrial applications.
Engineered for pulp & paper, oil & gas, chemical, petrochemical, mining, and LNG.
Industrial Segment Ball Valves Designed for Performance and Reliability
Nordenflow segment ball valves deliver the perfect balance between the simplicity of a ball valve and the precision control of a globe valve
The engineered V-notch segment provides powerful shear action that easily cuts through fluids containing fibers, particles, or slurry—making it ideal for applications where traditional control valves fail.
With wide rangeability, high flow capacity, and stable modulating performance, this valve class is built to maintain control accuracy even under rapidly changing process conditions.
If your operation requires robust control, low maintenance, and stable performance in harsh environments, this is the valve designed to handle it.
Technical Highlights:
- Sizes: DN25 – DN500
- Pressure classes: PN16 – PN63 / ANSI 150 – 600
- Design: V-port segment ball, one-piece or two-piece body
- Flow characteristic: Equal percentage
- Actuation: pneumatic (with positioner), electric, or electro-hydraulic
- Body materials: WCB, CF8, CF8M, CF3M, etc
- Applications: Liquids, slurries, fibers, chemicals, gases, steam (depending on trim)
- Shotoff class: Class IV or V
- End Connection: Flange Type/ Wafer Type
- Certifications: ATEX / PED / SIL (with actuator package)
- Trim & Shaft Materials: Stainless steel, hardened alloys
Commercial Advantages for Industrial Operations:
1. Strong shear capability for challenging media
The V-notch segment cuts through fibers, pulp, slurries, and solids—ideal for the pulp & paper industry and difficult service media
2. Excellent rangeability and flow control
Achieve stable modulation across wide flow variations, ensuring process consistency
3. High flow capacity
Segment ball geometry enables higher Cv compared to globe valves of the same size—reducing valve size and cost
4. Robust, low-maintenance design
Self-cleaning action reduces clogging and lowers downtime and operational expenses.
5. Flexible actuation and automation
Supports pneumatic, electric, and electro-hydraulic actuators with smart positioners and control system integration.
6. Suitable for severe service conditions
Available with hardened trims, corrosion-resistant materials, and options for high-pressure or abrasive service.
