Sofis, the experts for valve operation applications in the process industry, relies on Pepperl+Fuchs sensors for its latest solution called “Valve Position Indicator” (VPI). VPI provides an overview of manual valve position in plant networks. With a combination of integrated sensors from Pepperl+Fuchs and an innovative counting mechanism that automatically detects valve stem rotation, VPI offers reliable valve position information. Due to highly visible LEDs, valve position can easily be read and reported to the control room. This prevents incorrect positioning of manually operated valves, reduces costs, and increases overall process reliability.
VPI can be used for indication of open and closed position as well as open or closed position. The highly accurate counting mechanism ensures that the open or closed signal is only initiated when a valve has actually reached its final position. This status indication can be individually configured using different types of sensors from Pepperl+Fuchs.
Thanks to a broad portfolio of inductive sensors with cylindrical or slot housing design and Ex i, Ex na, versions, users can solve individual applications with maximum flexibility. A wide temperature range of -50 … +100 °C and versions for safety applications up to SIL 3 make the devices suitable for the most challenging conditions.
These sensors are part of Pepperl+Fuchs’ comprehensive portfolio that is tailored to the process industry and valve positioning in particular. Regardless of the location or drive, the range covers products for indoor, outdoor, and extreme conditions. Extensive engineering know-how and decades of experience in explosion protection ensure an absolutely reliable application solution.
VPI housings are made of coated aluminum or AISI 316L stainless steel and protect electrical and mechanical components from harsh industrial environments. Thanks to a universal mounting kit for every valve type, VPI can be installed quickly and used anywhere.
