Rotork, a global actuator manufacturer and flow control company with locations throughout the US, has introduced the SPI Smart Position Indicator, designed to assist refinery operators in monitoring manual valve positions in their plants.
The SPI has a large dial display to show the valve position locally and one or two internal switches or sensors for remote indication. A fully sealed aluminum enclosure is designed to provide an accurate valve position signal and uses the same ISO 5210 valve adaption as used for electric actuation, which is considered more robust than alternative “arm” methods.
