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, and ball seat for
damage or wear (
Figure 110 and Figure 111 ).
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 110 and Figure 111 ).
3. Install the valve stem and seat it into the
manifold and secure the stem and seat with the
stem retainer (
Figure 110 and Figure 111 ).
4. Ensure that the back seating O-ring and the ball
seat are aligned and seated into the end-cap
fitting (
Figure 110 and Figure 111 ).
5. Install the end-cap-fitting assembly onto the
manifold body until the flange of the end-cap
fitting touches the manifold body, then turn the
end-cap fitting an additional 1/8 to 1/4 turn
(
Figure 110 and Figure 111 ).
Note:
Use caution to prevent damaging the
end of the fitting.
6. Insert the ball into the valve body ( Figure 112 ).
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 112 ).

7. Turn the valve-stem assembly so that the valve
is closed (B of
Figure 109 ).
8. Repeat steps 4 and 5 for the other end-cap-fitting
assembly.
Installing the Section-Manifold
Valve
1. Align the 2 gaskets that you removed in
Removing the Section-Manifold Valve (page
77)
to the flanges of the section-valve manifold
( Figure 113 ).
Note:
If needed, loosen the mounting hardware
for the left or right section-valve manifolds as
needed to provide clearance.

2. Align the flange of the section-valve manifold
between the flanges of the other section-valve
(s) and/or coupling adapter (
Figure 113 ).
3. Assemble the quick-connect fitting of the
section-valve manifold to the quick-disconnect
socket of the section-bypass valve with a
quick-connect pin (
Figure 113 and Figure 114 ).
