4. ACCESSORIES
4.1 100% Adjustable Stop (AS)
The standard Quadra-Powr can be configured in the field
for a 100% adjustable stop. Remove the set screw plug (35)
with an allen wrench. Thread in the adjustable stop screw
enough to reach the desired stop position and allow room
for the lock nut. Screw on the lock nut for the adjustable
stop and tighten to secure it in place.
4.2 Mechanical Lockout (LD)
The standard Quadra-Powr can be configured in the field
for a locking device to lock the actuator in its failsafe
position. Installation of the locking device does not require
adjustment of the standard open/close limit screws.
Installation (see Figure 3)
1. Before attempting to assemble lockout devices, make
certain that the actuator is not pressurized.
2. Remove the plug (80) using an allen wrench.
3. Remove the lower jam nut from the locking stud.
4. Insert the locking stud through the hole in the locking
plate. Thread the locking stud into the lockout hole and
tighten securely. Tighten the upper jam nut to secure
the locking plate. Pivot the locking cover down until the
hole in the cover lines up with the hole in the end of the
locking plate.
5. Secure the locking device with a padlock. A padlock
with 1/4" – 5/16" (6.35 – 7.9mm) diameter shackle is
recommended.
Removal and storage (see Figure 4)
1. Remove the padlock and swing the cover out of the way.
2. Loosen (do not remove) the upper jam nut and then
remove the locking stud.
3. With the locking stud still inserted through the large
hole in the locking plate, thread the lower jam nut onto
the bottom of the stud. This will secure the stud and
nuts for storage.
4. Re-insert the plug (item 80) into the locking hole. The
wire tie can be secured to the plug for storage of the
locking device.

4.3 1" NPT Air Inlet (F)
NOTE: Applicable only to QPX size 3 – 5.
Remove the 3/8" Reducing bushing (Item 37) to access the
1" NPT port.
4.4 Manual Jackscrew Override (MJX)
Figure 5.
The MJX is intended to move the valve upon failure of the
actuator, supply air, or electrical system. When the handwheel
of the manual jackscrew is turned clockwise, force is exerted
on the diaphragm retainer, compressing the actuator spring
and operating the valve in the direction of the air stroke.
