Pneumatic Automation Concepts Comparison

This white paper presents a comparison of individual valves and valve terminals for actuating pneumatically automated process valves. It addresses the technological and economic differences between these two options, including a cost comparison and commissioning considerations. The paper discusses the advantages of using valve terminals, particularly in safety instrumented systems (SIL), and outlines practical examples of their application. It highlights that valve terminals facilitate decentralized automation, allowing for quick setup and integration. The document details the benefits of valve terminals, such as flexibility, time savings, safety, reduced installation effort, and maximized system availability through diagnostics. A cost analysis is provided, showing significant savings when using valve terminals, especially in systems with closely positioned valves. The paper also emphasizes the importance of proper planning and installation to avoid costly operational issues. Overall, it serves as a comprehensive guide for understanding the implications of choosing between individual valves and valve terminals in pneumatic automation.
