Page 10: Dismantling The Actuator Off The Valve
For all the installations carried out here, the actuator must be taken off the valve (see chapter 4.2). If the operating mode or the spring force has been altered, the type label must also be altered. 4.4.1 PA-N 160 and PA-N 280 without manual positioning The following steps are necessary to dismantle the actuator: •... - Page 11 • For operating mode SO: Remove top cover (14). Pull the spindle components with the braced parts (1 – 8) from the cover bottom (11). Remove the spring centring sheets (12) and the pressure springs (13) from the cover bottom (11). If the guide is to be replaced (10), undo the groove nut (19) and pull the guide (10) from the cover bottom (11).

4.4.2 PA-N 160 and PA-N 280 with manual positioning The following steps are necessary to dismantle the actuator: • Bring the manual positioning in zero position (turning safeguard (34) and marking on the column (20) at the same level). To do so, first unlock drop-in pin (45). -
Page 13: Maintentance
5.2 Maintentance The pneumatic actuators are low-maintenance. The guide (10) and the membranes (4) are consumables have to be replaced if necessary. To ensure continuous readiness for use of the manual positioning, we recommend to check the greasing situation of the threaded spindle (32) every 3 months and, if necessary, put grease directly onto the thread. The spindle is lubricated at the factory. -

Page 22: Specification, Technical Data
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. 3.2 Function &... - Page 23 Operation Operation Fig. 3: Actuator Type PA-N 1080 SO & SC without and with Manual control 9 / 19...

Page 28: Removing The Actuator From The Valve
4.2 Removing the Actuator from the Valve • Move the actuator into the central position using air pressure. Danger Ensure that compressed air cannot escape accidentally from the actuator. A pressure drop in the actuator can cause prestress between the valve and actuator spindle (1) and ejection of the coupling (22) (if the cheese-head screws (23) have been removed). - Page 29 • With SO operation: Remove the upper casing (16). Remove the spindle assembly together with the screwed parts (1 – 8) from the lower casing (12). Take the ring (13) and the pressure springs (14 and/or 15) from the lower casing (12). Should the guide (10) and/or screw connector (11) need to be renewed, unscrew the screw connector (11) and remove the guide (10) from the lower casing (12).
