1. Fig 1 Actuator Handling If the actuator is mounted on a valve the chain hoists used for fitting the subassembly are to be attached to the valve 7 19 3 Specification Technical Data 3 1 Application Pneumatic control actuators are designed directly for actuating control valves They are particularly suitable for utilisation in control systems in the chemical industry They achieve high actuating powers with short actuating times A safety position is also assured in the event of actuating pressure failure by the springs 3 2Function amp Operation Pneumatic actuating signals are converted into thrust motion by the pneumatic piston actuator The required return force is produced by the pressure springs located on the diaphragm disc In the event of air supply failure the actuator is reset to the default position by spring force The actuator mode of operation i e spring opens air closes SO or air opens spring closes SC is achieved depending on the mounting of the springs The mode of operation of actuators already fitted to systems can be changed without additional components using simple tools 3 3Section Drawings with Piece Lists Operation Operation SO SC SO SC
