The SPI of the rotor torque reliably displays the opening degree of the manual valve without interruption.

Rotolock has released the SPI Smart Position Indicator, making significant improvements in robustness, reliability, and accuracy. By installing the SPI, it is possible to monitor any valve within the refining plant from the control center, leading to improved operational control accuracy. The SPI features a large digital display, allowing for the verification of valve opening on-site. It also includes one to two built-in switches or sensors for remote display. Furthermore, it is completely sealed in an aluminum housing, accurately outputting the valve position signal. For large valves with a gearbox, the installation position of the SPI is at the input flange of the gearbox. For small valves, it can be directly mounted on the valve, and for stem rising valves, an optional thrust base is also available. The SPI uses the same ISO5210 valve mounting as electric actuators, which is more robust than traditional arm types. The SPI has an environmental resistance rating equivalent to IP67, and as a sister version, we offer an IECEx/ATEX explosion-proof unit for hazardous locations.
