Globe and piston valves are used in industry to regulate and shut off the flow of liquids and gases. Globe valves are particularly suitable for control purposes and precise flow regulation, whereas piston valves function efficiently as shut-off valves and are suitable for high flow rates. Both valve types are key components in modern process industries and industrial automation.
The role of globe and piston valves in industry
Globe and piston valves together form a versatile and comprehensive solution for demanding flow control applications in the process industry.
Globe valves are ideal for both shut-off and control use. Their linear operating principle – the movement of the valve stem through the seat – enables precise flow regulation and high tightness. This makes them excellently suited for applications such as steam and condensate, where the combination of controllability and sealing is critical.
Piston valves, on the other hand, operate with a rotary motion in which a disc- or plug-type piston opens and closes across the flow path. The design of KLINGER’s piston valves is based on decades of experience and continuous technical development, which ensures their high reliability and long service life even under demanding conditions. Thanks to their structure, they are also suitable for contaminated media where traditional globe valves often face challenges.
These valve types play a central role in critical processes where precision, safety, and efficiency are of utmost importance. Both valve types integrate seamlessly into automation systems, enabling remote operation, process optimization, and improved energy efficiency. They are an established part of reliable and flexible flow control solutions across various industries.
What are the main applications of globe and piston valves?
The applications of globe and piston valves cover a wide range of industries where reliable flow control is critical:
- Oil and petrochemical industry: For regulating flammable liquids and gases under high pressure.
- Pharmaceutical industry: Ensuring clean processes and preventing contamination.
- Pulp and paper industry: Controlling the flow of steam and chemicals in production processes.
- Water treatment: Regulating chemical dosing and process flows.
- Energy sector: Managing steam and hot liquids in power plants.
- Mining and steel industry: Withstanding harsh conditions and high-pressure applications.
How do globe valves differ from piston valves in practice?
Globe and piston valves differ significantly in their operating principles and suitability for various applications. Globe valves offer excellent modulation and sealing capabilities, while piston valves are more effective in on-off service.
Globe valves are best suited for applications that require precise flow control and tight shut-off. Piston valves excel in high-flow applications and where fast opening and closing is required.
Key benefits and applications in industrial automation
Globe and piston valves provide significant advantages in industrial automation, including precise process control, improved safety, and energy efficiency. These automation valves enable remote control and real-time process monitoring.
Choosing the right valve type depends on the requirements of the application. Globe valves are recommended for control applications due to their precision. Piston valves are suitable as shut-off valves and in applications where minimizing pressure loss is important.
Both valve types support digital automation and integrate easily into existing systems. They improve process reliability and reduce the need for maintenance when properly selected and installed.
