Operations Schematic Diagram
When the piping and flow control system working properly, the gear operator is placed in auto mode. The pressed air paths are as following:
  • Filter regulator.
  • Safety shift gear operator (P-A).
  • Solenoid valve.
  • Pneumatic actuator.
When the piping and control flow system in failure, we should shift the gear operator to manual mode by turning the shift handle. At this moment, the air flow path (P-A) is completely blocked safely, (A- R) provide a exhaust path for the actuator. The safety shift device built into the body of gear operator which follows IP67 protection standard, free from impact or any bad working conditions.
