Re-Assembly
1) Install stem bearing on to stem.
2) Fit stem into body from the retainer end and position the stem
with the handle flats perpendicular to the flow axis.
3) Install stem packing over stem and fit into body recess.
4) Install packing gland screw into the threaded stem area.
5) Tighten the gland screw to the torque specification shown in
Table 2.
6) Install the handle and handle retaining hardware.
7) Apply suitable light lubricant to seat and fit into the seat pocket
of the body.
8) Install the ball in the closed position.
9) Apply suitable light lubricant to seat and fit into the seat pocket
of the retainer.
10) Apply an adequate amount of thread locking compound
(Loctite® 609, 648 or 680) to the retainer threads so that it
covers no less than two complete threads opposite of the
retainer shoulder.
11) With the ball in the closed position, thread the retainer into the
body and torque to manufacturing specification to secure the
body joint. Torque the retainer to the torque specification in
Table 3.
12) Cycle the valve to the open position and verify proper operation
and alignment of handle and/or mechanism.
Note: Valves in oxygen or other like services should be
assembled with compatible thread sealant and lubricants.
Note: Always test valve and system before putting the system into
service.
