3. Turn the valve stem so that the ball is in the
open position (
Figure 71 A).
Note:
When the valve stem is parallel with the
valve flow, the ball slides out.
4. Remove the stem retainer from the slots in the
stem port in the manifold (
Figure 72 and Figure
73 ).
5. Remove the stem retainer and valve stem seat
from the manifold (
Figure 72 and Figure 73 ).
6. Reach into the manifold body and remove the
valve-stem assembly (
Figure 72 and Figure 73 ).
7. Clean the inside of the manifold and exterior
of the ball valve, valve-stem assembly, stem
capture, and end fittings.
Assembling the Manifold Valve
1. Check the condition of the outlet-fitting O-rings
(section-valve manifold only), end-cap O-rings,
back seating O-rings, ball seat for damage or
wear (
Figure 72 and Figure 73 ).
Note:
Replace any damaged or worn O-rings
or seats.
2. Apply grease to the valve stem and insert it into
the valve-stem seat (
Figure 72 and Figure 73 ).
3. Install the valve stem and seat into the manifold
and secure the stem and seat with the stem
retainer (
Figure 72 and Figure 73 ).
4. Ensure that the back seating O-ring and the ball
seat are aligned and seated into the end-cap
fitting (
Figure 72 and Figure 73 ).
5. Install the end-cap-fitting assembly onto the
manifold body until the flange of the end-cap
fitting touches the manifold body (
Figure 72
and Figure 73 ), then turn the end-cap fitting an
additional 1/8 to 1/4 turn; torque the fitting to 225
to 282 N∙cm (20 to 25 in-lb).
Note:
Use caution so as not to damage the end
of the fitting.
6. Insert the ball into the valve body ( Figure 74 ).
Note:
The valve stem should fit inside the ball
drive slot. If the valve stem does not fit, adjust
the position of the ball (
Figure 74 ).

7. Turn the valve-stem assembly so that the valve
is closed (
Figure 71 B)
8. Repeat steps 4 and 5 for the other end-cap-fitting
assembly.
