Control Valve Solutions for Precise Flow and Process Control
Engineered Flow Control & Process Automation Valves
At Nordenflow, we provide control valve solutions engineered to regulate flow, pressure, and process conditions under real operating environments.
Control valve selection is not based on valve type alone—it depends on flow characteristics, pressure drop, control accuracy, and process stability requirements.
The right valve defines how the system responds under changing conditions, not just how it operates at a fixed point.
Choose the Right Control Valve Type
Control valve selection depends on flow behavior, pressure conditions, and required control accuracy. Each valve type is suited to specific operating conditions and process demands.
Globe Control Valves
Designed for precise flow modulation and stable control across varying process conditions.
→ Best for applications requiring high control accuracy and repeatable performance.
Segment Ball Valves
Suitable for high-capacity flow control and handling of challenging media such as slurry or viscous fluids.
→ Best for applications requiring higher flow rates with lower pressure drop.
Triple Offset Butterfly Valves
Engineered for severe service conditions requiring tight shutoff and reliable operation under high temperature or pressure.
→ Best for critical applications with demanding operating environments and shutoff requirements.
Engineering Approach to Control Valve Selection
Effective control valve selection is based on how the valve behaves under changing process conditions. Key parameters such as flow capacity, pressure drop, control characteristics, and shutoff performance must be evaluated together to ensure stable and predictable operation.
Flow Coefficient (Cv)
Determines the valve capacity required to achieve target flow rates under defined pressure conditions without oversizing.
Pressure Drop Management
Proper allocation of pressure drop across the valve ensures controllability and prevents instability or cavitation risks.
Control Characteristic
Linear or equal percentage characteristics are selected based on process dynamics and required control accuracy.
Rangeability
Defines how effectively the valve can control flow across varying operating ranges without loss of stability.
Shutoff Performance
Required leakage class determines seat design and valve type, especially in applications where tight shutoff is critical.
Process Stability
Interaction between valve response and system dynamics must be considered to avoid oscillation or control loop instability.
Applications
Control valves are used to regulate flow, pressure, and temperature across a wide range of industrial processes where stable and responsive control is required.
Pulp & Paper — Process Flow & Consistency Control
Control of pulp consistency, chemical dosing, and steam flow in digesters and drying sections where stable operation directly impacts product quality.
Oil & Gas — Flow and Pressure Regulation
Control of gas and liquid flow in upstream and processing systems, including pressure regulation and separation processes.
Power Generation — Steam & Energy Control
Regulation of steam flow and pressure in boilers and turbines, where precise control is required for efficiency and safety.
Chemical & Process Industry — Reaction Control
Accurate dosing and flow control in chemical reactions where stability and repeatability are critical to process performance.
Water & Utilities — Flow Distribution
Regulation of flow and pressure in water treatment and distribution systems requiring reliable and continuous operation.
Nordenflow delivers control valve solutions tailored to real process behavior, ensuring stable control, reliable performance, and proper integration into industrial systems.
