15. Install O-Ring (21) over core tube (24) and
into its O-Ring groove.
16. Insert two screws (17) through coil S/A (18).
Place gasket (19) over the screws and assemble coil over
core tube. Thread coil wires into body cavity. Torque screws
to the value shown in parts drawing.
NOTE
The following steps (17 through 25) pertain to (B &
C) spring centered models.
17. Install O-Ring (13) on manual plunger (12).
Lubricate with petroleum jelly.
18. Insert manual plunger (12) into hole at the
bottom of core tube (7) with the shoulder of the plunger on
the inside of the core tube.
19. Install armature (11) into crore tube as shown.
Make sure the armature fits over the manual plunger at the
bottom of the core tube. Use correct armature S/A for AC
and DC operation. See parts drawing.
20. Install pole face (10) into core tube (7) on top
of armature (11).
21. Insert push pin (9) into pole face hole.
Assemble O-Ring (8) in groove of pole face.
22. Assemble flange (6) on core tube (7) with
chamfer side facing body (38).
23. Assemble core tube (7) and flange (6) against
body (38) with screws (5). Torque screws to value shown in
parts drawing.
24. Install O-Ring (4) over core tube S/A (7) and
into the O-Ring groove.
25. Insert two screws (1) through coil S/A (2).
Place gasket (3) over the screws and assemble coil over
core tube. Thread coil wires into body cavity. Torque screws
to the value shown in parts drawing.
b. Spring offset “A” models
:
See Figure 18.
NOTE
Observe the model code. If left hand (LH) assembly
is required, reverse all pilot parts except body and
spool.
1. Install O-Rings (35 and 37) on plugs (34 and
36). Lubricate plug threads and install into body (38) as
shown. Torque the plugs to valve shown in parts drawing.
2. Lubricate the pilot spool (33), then carefully
install spool into the body bore. Orient small end of spool
toward cover (18a).
3. Install spring (30) into body bore.
4. Assemble O-Ring (19a) into groove of cover
(18a). Lubricate O-Ring with petroleum jelly and place cover
against end of valve body (38). Thread screws (17a) through
cover into body and torque to the value shown in parts
drawing.
5. Assemble and install solenoid S/A parts and
coil S/A. Perform steps a.17. through a.25.
c. Detent “N” models
:
Refer to Figure 18.
1. Install O-Rings (35 and 37) on plugs (34 and
36). Lubricate plug threads and install plugs into body (38)
as shown. Torque the plugs to valve shown in parts drawing.
2. Lubricate the pilot spool (33), then carefully
install spool (33) into the body bore. Polished end of spool
must face detent (15a) end of valve.
3. Install spring (14) and detent (15a) over end of
valve spool.
4. Assemble spacer (31) over the end of spool
(33) with chamfered end of spacer facing push pin (25).
5. Assemble core tubes and coils to ends of the
valve. Perform steps a.9 through a.11 and a.15 through a.25.
3. Assembly of Pilot Valve to Main Stage Section:
Refer to Figure 15.
a. Apply a heavy amount of petroleum jelly to
O-Rings (5) and pilot valve mounting face grooves. Install
O-Rings into pilot valve.
b. Assemble a lock washer on each of the four
screws (4). Lubricate screw threads and insert screws
through pilot valve body.
c. Line up the port holes and screw holes. Make sure
O-Rings do not slip out of position. Attach pilot valve to main
stage section and thread screws into valve hand tight.
Torque screws evenly to value shown in parts drawing. DO
NOT OVER TORQUE.
d. Mount the two stage valve on a manifold or
subplate. Refer to installation drawing, Table 1, for
instructions and bolt kit number.
e. Connect electrical power to solenoid wire leads. If
an air operated pilot valve is used, connect the air lines to
the connection plate.
f. Install nameplate (2) and gasket (3) on pilot valve
body if previously removed.
g. Insert four screws through nameplate (2) and
gasket (3). Secure nameplate to the pilot valve body.
