Automation for the requirements

in the process industry

Number one choice as a control valve:
Designed for the toughest demands – even in extreme environments.
Certificates, expert opinions and testimonials demonstrate that the solenoid
valves are suitable for the toughest demands when it comes to operational
safety, availability and flexibility in use. Even outdoors and in difficult
ambient conditions. The world’s most widely recognised ignition protection
types are offered: Ex e mb, Ex ia, Ex db und Ex d.

Individual valves or valve terminals – which is the most suitable option for actuating pneumatically automated process valves? What are the technological and economic differences between the two? We will use a cost comparison to compare and contrast the two options. And what are the differences in terms of commissioning? Which diagnostic options are available with valve terminals for reducing unscheduled downtime? These are the questions that will be examined in this article.

On/off process valves can be automated in different ways using pneumatics. This white paper looks at automation using an individual valve, a valve terminal and a digital valve terminal, and compares the three actuation methods in terms of:

• Required hardware/components and the installation

effort involved

• Investment costs

• Potential for compressed air savings and increased

energy efficiency

• Diagnostic and maintenance options

• Potential for function integration

• Possible applications in safety-related circuits

• Possible applications in potentially explosive areas
