REPAIR PROCEDURE – ASSEMBLY
—
1. Before beginning assembly, clean the internal
body surfaces (P14) and the parts not supplied
in the kit with isopropyl alcohol (S3).
2. Begin assembly by making sure the O-ring
between the diaphragm and retainer is evenly
in place. Snap O-ring pre-set tool (P15) on stem
(see Figure 4). Then position the diaphragm/
retainer/stem assembly (P7) into the body (P14),
lining up the tabs on the retainer with the slots
on the body (P14).
3. Thread the retainer nut (P13) into the body (P14)
until the retainer nut (P13) just contacts the
retainer. See Figure 3.
4. With the retainer nut adaptor (T2) tighten the hex
portion of the adaptor to 5.65 N•m (50 in•lbs)
using the torque wrench (S4) and 1⁄" crow’s foot
(S5). Discard O-ring pre-set tool (P15).
5. Thread the actuator nut (P6) onto the stem until
it bottoms out.
6. Place the thrust washer (P5) onto the actuator
nut.
actuator nut (P6) first lines up with the hex on
the stop nut (P2).
15. Install the handle (P8) so that the holes in the
handle line up with the holes in the collar halves
(P9).
16. Insert two screws (P1).
17. Proceed to test the valve.
P8 Handle and
P2 Stop nut removed
P9 Collar half
S1 Screwdriver
7. Place the inner cap (P12) onto the valve body,
aligning the bosses on the body with the slots in
the cap.
8. Install the outer cap (P11) and slowly torque to
13.5 N•m (120 in•lbs) using the torque wrench
(S4), 1⁄" crow’s foot (S5) and outer cap wrench
(T1).
9. Turn actuator nut (P6) clockwise until it contacts
the inner cap (P12).
10. Place O-ring (P4) and thrust washer (P3) into the
groove on the inner cap (P12).
11. Install collar halves (P9) onto the stem as shown
in Figure 5.
12. Thread on the panel mount nut (P10).
13. Set up valve so that 552 kPa (80 psi) can be
applied to the outlet port.
14. Place the handle (P8) onto the actuator nut (P6)
and slowly close the valve until a seal is just
made. Remove the valve handle without disturbing the stem position, and turn the stop nut (P2)
clockwise until it first contacts the actuator nut
(P6). Then turn the stop nut (P2) counterclockwise less than ⁄ of a turn so the hex on the
