thickness of the sandwich block for the holes to be open.

Pilot Pressure Supply
This valve requires a source of air pressure for shifting - a pilot supply.
The sixth character in the model number identifies this supply when the
valve was assembled at the factory. If changes have occurred in the field,
the character will no longer represent that pilot arrangement. If a new
valve is ordered with the same model number as the old one, perform an
examination at the time of replacement and move the plugs (if necessary)
so that the new valve has them in the same locations as the old one
(described in steps 1-3 following).
Conversion in the field from an internal pilot supply to an external type, or
vice versa, is possible. However, conversion from a single pressure valve
to a dual pressure type is not possible in the field - special parts are
required. (However, dual pressure valves can be converted back to single
pressure in the field.) All of these conversions are performed by relocating
small plugs as follows:
1.
The bottom surface of the sandwich block has several holes which
receive the small plugs. This is accessed by loosening the three main
body mounting screws (item A) with a 4 mm hex wrench and removing
the valve from its base. These holes have identification alongside as
shown in Figure 4 and plugs must be located in the holes as described
in Table 1. (See the two identification methods located in Table 1.)
2.
To remove a plug, insert a narrow tool under the side of the nib and
pry it upward slightly. Then, grasp the projecting nib (long nose pliers
may help) and pull it out. Examine the o-ring to be sure it is not torn
or nicked, and that it has a coating of grease. Install the plug into the
appropriate hole (o-ring end enters first) by pushing it in place until it
comes to a stop and the nib is flush with the surface of the sandwich
block.
3.
Replace the valve on its base, making certain first that the interface
gasket (item B) is in place in it’s grooves in the sandwich block.
Engage the electrical plug carefully during this process. Tighten the 3
main body mounting screws from 2.9 to 3.8 N•m (25 to 35 in-lbs).
4.
Apply main pressure and check for leaks. If any are present, do not
operate the valve - repeat the reassembly process until satisfactory.
