VPI position indicator

Real-time position feedback of your manual valves. Get up-to-date valve status information, improve process performance and increase right first time procedures.

Send real-time valve position information to your DCS

VPI is a high-performance switch box for manual multiturn valves. It detects when valves have reached their open or closed position and sends a signal to your DCS. This valuable information about manual assets enriches your control system’s capabilities. It helps to further optimize your process performance, and prevents safety issues or product contamination caused by incorrect valve line-ups.
