SAC, Servi Addon Components - presentation and user manual/datasheets

Servi provides valve technology that ensures improved accuracy, repeatability, response and performance.
Servi’s range of SAC (Servi Addon Components) supplementary components consists of electronic units with BUS communication – ODC (Onboard Digital Controller) and OPAT (Onboard Profibus Atex Twinsolenoid) – that can be installed directly on the valves (OBE – On Board Electronics). The casings are solid and designed for use in harsh marine and offshore environments.

The SAC program includes an HPRS type (High Performance Range Sensor) sensor that is integrated into the valve. The HPRS contains an LVDT with extraordinary precision and 4-20 mA sensor signal.

Our customers are extremely satisfied with the OPAT and HPRS. Customer machines that already meet high standards of performance and precision double their performance in terms of speed and accuracy after such an upgrade. Also available with ATEX/IECEx certification.
