Globe Control Valves Series
Pneumatic Globe Control Valves
Driven by pneumatic actuators, the plug moves precisely for accurate throttling and tight shut-off under high-pressure, high-temperature conditions — delivering fast response, stable control, and maintenance-free performance.
Electric Globe Control Valves
Powered by electric actuators, the plug travels linearly for precise modulation and bubble-tight shut-off in demanding process lines — offering accurate control, easy automation, and long service life.
Typical Applications for Globe Control Valves in Flow Control
Petrochemical
In the petrochemical industry, globe control valves ensure stable flow control through erosion-resistant designs, enabling reliable process control and operational safety.
Energy & Power
In power and energy applications, globe control valves are primarily used for regulating steam and cooling water circulation, ensuring stable unit operation.
Pulp, Paper, and Metallurgical
In the pulp and paper and metallurgical industries, globe control valves provide precise control of pressure and flow.

What is a globe control valve?
A globe control valve is designed to accurately regulate fluid flow by moving a plug toward or away from the valve seat. It features high control precision and reliable sealing performance, making it ideal for stable and precise flow control applications.
What are the advantages and limitations of a globe control valve?
Globe control valves offer excellent throttling accuracy and tight shutoff, ensuring reliable performance. However, they typically have a higher pressure drop, making them less suitable for large flow rate systems.
What flow characteristics are available for globe control valves?
Globe control valves are available with different flow characteristics, which describe how the flow rate changes as the valve opens. The main options include linear, equal percentage, and quick opening, allowing precise flow control under different operating conditions.
Linear: Flow increases proportionally with valve travel, suitable for stable systems with constant pressure.
Equal percentage: Provides fine control at low openings and high capacity at large openings, ideal for variable pressure applications such as steam and temperature control.
Quick opening: Delivers high flow at small openings, mainly used for on-off or bypass service.
Flow characteristic comparison
| Flow Characteristic | Control Precision | Pressure Drop Adaptability | Typical Use |
|---|---|---|---|
| Linear | Medium–High | Low | Stable systems |
| Equal Percentage | High | Excellent | Steam / temperature control |
| Quick Opening | Low | Poor | On-off / bypass |
Where are globe control valves commonly used?
They are widely applied in power generation, petrochemical, and water treatment industries—fields that require precise flow regulation and stable operation.
How do I choose the right globe control valve?
Consider the medium type, working pressure, temperature, and desired flow control accuracy. For example, hygienic globe control valves are used in food and beverage applications with strict sanitary requirements, while corrosion-resistant globe valves are recommended for chemical or petrochemical processes with aggressive media.
