F25—Compact, Open Solutions for Valve Position Signaling


The F25 series in a compact housing design

Requirements in the process valve market are demanding. Some solutions require explosion protection, while others require a compact design, and still others have to withstand harsh conditions in outdoor environments. To meet these requirements, Pepperl+Fuchs offers a range of open solutions for valve position signaling. In addition to the F31/F31K and F31K2 product families, our portfolio is completed by the compact F25.

Small Valve Actuators Require Compact Solutions

Small valve actuators require inductive sensors that are compact, durable, and flexible. As an open solution for valve position signaling, the F25 is mounted directly on the actuator and detects whether the pivot valves are open or closed. Given the choice between cable, plug, or plug-in terminal connections, as well as the variety of actuators and a complete range of accessories, it offers maximum flexibility for application-optimized solutions.

Your Benefit: maximum flexibility and a wider range of possible applications.

Adapted to the User's Needs

The clearly visible corner LEDs enable an application-optimized display of the power supply and the sensor status. The innovative and user-friendly "Puck+Beacon" concept provides high-visibility valve position display.

Your Benefit: simplified field diagnostics and a valve position display that is visible from a distance.

The Best of Both Worlds

The F25 offers a high level of compatibility as it can be easily integrated into all common control systems. The Pepperl+Fuchs solution achieves this by combining inductive, noncontact sensor technology with extremely low-voltage outputs. In other words, the benefits of inductive, noncontact sensor technology are combined with the functionality of mechanical switches with minimum power consumption when switched off. This combination means that no expensive modification of existing systems is necessary.

Your Benefit: the F25 combines the advantages of both electronic and mechanical systems in one open solution.

Time-Saving and Economical Mounting

The F25 allows simple and convenient mounting in only a few steps. The captive screws in the F25K and the protective housing of the "Puck+Beacon" concept can save time and money.

Your Benefit: quick and convenient mounting, maximum convenience in the minimum amount of time.

Strong, Durable, and Reliable

The F25 series is distinguished by its reliability and durable design, as well as by its IP67 protection rating. It is particularly durable due to its reinforced plastic housing.

Your Benefit: suitable for harsh outdoor environments.
