Orbinox’s PNEUTON™ engineering team has just completed the 3D models for its next contract. This 20″ class 600 ball valve will be automated with a BETTIS™ GH7128-SR4 single acting scotch yoke pneumatic actuator. The local controls include a 1:1 ratio filter volume booster c/w closed loop breather system.
The instrument panel will be remote mounted on this occasion, and was designed to meet the project specific logic, and included the DVC6205 SIS positioner c/w LCP100 electrical control panel. An air reservoir was sized to accommodate the positioner’s static air consumption over an agreed time frame, to ensure the ESDV remained open under a catastrophic air failure event. Its application is the ESD valve on a crude export pipeline, situated on an off-shore platform.
