AAMM-01 and Advantage ® Actuator Maintenance Manual This manual provides installation and maintenance instructions for ADV ANT AGE ® ACTUA TOR operated diaphragm valves.
2 CAUTION - WELD END V AL VES Weld end valves for schedule 10 and heavier pipe require actuator removal prior to welding in line. Schedule 5 and lighter pipe and tubing may be welded with automatic equipment only without removing the actuator . The valve must be in the open position and properly purged with an inert gas.
3 3.3 Diaphragm-Flange Leakage If valve diaphragm flange area leaks, depressurize system and open valve slightly , using the wrench opening device (3” & 4”Series 47 only , DIN 80 & 100 only) or a local bleed type regulator . Tighten bonnet bolts as described in Section 1.
4 the cover bolt holes with no stretching of the diaphragm. The compressor extends 0.72” from the bonnet face in this relaxed position, reference p. 10 for a view of the compressor position. Re-assembly is the reverse of the above, use Blue Loctite #242 on the spindle nut.
5 and 2” (DIN 40 & 50) sizes require four (4) threaded rod guides in the lower cover prior to assembly . Position the actuator sub-assembly , including spring(s) and top cover , over the spacer (i.

Then back off until bolt holes in diaphragm and bonnet register . 3.8.1.5 Reduce air pressure until back of diaphragm is flat against bonnet.
7 use Blue Loctite #242 on the spindle nut. The diaphragm is to be assembled top hat up. See T able 1 for fastener torques. 3.8.4 Spindle O -Ring Replacement (All sizes) 3.8.4.1 Disconnect air lines. Remove actuator from valve body and dismantle actua- tor following instructions above for removing actuator diaphragm and spring.
