Advanced Technologies for Valve Position Feedback

Valve Position Feedback

Monitoring the status of valves is an essential task in any process plant. That is why Pepperl+Fuchs offers a broad portfolio of products tailored to valve position feedback, regardless of location or valve type. The sensors are available for indoor and outdoor use as well as for applications in harsh industrial environments. They are suitable for valve position feedback on standard pneumatic and manually operated valves, as well as on linear valves in applications with stringent hygiene requirements. In-depth engineering knowledge and many years of experience in explosion protection ensure absolutely reliable solutions.

There are various options for monitoring the position of valves: Choose between dual sensors, which combine two overlapping inductive sensor elements, and other solutions such as inductive sensors or inductive positioning systems.

Learn more about the portfolio and find the perfect solution for your individual application requirements!

Valve Position Feedback with Dual Sensors

Dual sensors combine two overlapping inductive sensor elements that detect the position of the actuator and therefore the position of the valve. The sensors, which are available with a highly visible position indicator, are typically used on standard pneumatic valves where they are mounted directly on the actuator. Pepperl+Fuchs offers variants designed for outdoor applications or hazardous areas.
