VPI position indicator

Reliable valve position feedback to your control room

The most reliable valve position indicator for linear valves

The VPI valve position indicator helps you to get a clear overview of the position of manual linear valves in the field. The mechanical counting mechanism of VPI is based on 20+ years of proven technology. It can be set very accurately so you only receive an open or closed signal once your valve has reached its end position.
