SPI Smart Position Indicator

The Smart Position Indicator is designed for use in chemical, petro-chemical, oil and gas industries, power plants and water supply.

Limit switches enclosed in a IECEx/ATEX certified protective enclosure provide an accurate and reliable Open/Close signal to the control room for multi-turn manual valves. Using 30+ years of proven technology, the new Smart Position Indicator mechanically displays the position of the valve for in-field notification and digitally signals its open/closed position.

With certification for use in gas and dust explosion hazardous environments,
