Reliable valve status information for linear valves

Reliable linear valve status information

  • 5 September 2017
  • Valve position monitoring

The VPI position indicator (VPI) provides process facility control rooms with a reliable remote signal, keeping personnel aware of the current position of hand wheel-operated gate valves.

Accurate valve status for new and existing valves

In the process industry, awareness of valves’ current status is essential to avoid injury and equipment damage. The VPI position indicator uses a mechanical counter to convert a valve’s open and closed positions to electronic signals. This ensures the accuracy of valve status signals sent to the control room. The device is mounted immediately below a valve’s hand wheel, without modification to the valve. The VPI position indicator  allows customers to choose whichever electronic switch they prefer. The VPI’s design eliminates externally mounted switches, weak welding, loose wiring and fragile brackets that cause false alarms in traditional monitoring systems. It can be mounted on both new and existing valves.
