F3 Sandwich Regulators
V-417DP
Pilot Pressure Supply
This valve requires a source of 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the character will no longer represent that pilot arrangement.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). If a sandwich regulator kit is being
used for an existing valve, examination and conversion is necessary per
the following.
1)
The bottom surface of the valve sandwich block has several holes
which receive the small plugs. These holes have identification alongside
as shown in the figure and plugs must be located in the holes as
described 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)
Re-assemble using Installation Instructions on page 4.
