3. Turn the valve stem so that the ball is in the
open position (
Figure 115 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 116 and Figure
117 ).
5. Remove the stem retainer and valve stem seat
from the manifold (
Figure 116 and Figure 117 ).
6. Reach into the manifold body and remove the
valve-stem assembly (
Figure 116 and Figure
117 ).
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
Operator supplied material: Clear silicone grease.
Important:
Use only silicone grease when
assembling the valve.
1. Check the condition of the outlet fitting O-rings
(section valve manifold only), end cap O-rings,
back seating O-rings, and ball seat for damage
or wear (
Figure 116 and Figure 117 ).
Note:
Replace any damaged or worn O-rings
or seats.
2. Apply silicone grease to the valve stem and
insert it into the valve stem seat (
Figure 116 and
Figure 117 ).
3. Install the valve stem and seat into the manifold
and secure the stem and seat with the stem
retainer (
Figure 116 and Figure 117 ).
4. Ensure that the back seating O-ring and the ball
seat are aligned and seated into the end-cap
fitting (
Figure 116 and Figure 117 )
5. Install the end-cap fitting assembly onto the
manifold body until the flange of the end-cap
fitting touches the manifold body (
Figure 116
and Figure 117 ), then turn the end-cap fitting an
additional 1/8 to 1/4 turn.
Note:
Use caution so as not to damage the end
of the fitting.
6. Insert the ball into the valve body ( Figure 118 ).
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 118 ).

7. Turn the valve stem assembly so that the valve
is closed (
Figure 115 B)
8. Repeat steps 4 and 5 for the other end-cap
fitting assembly.
