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 123
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
124).
3.
Install the valve stem and seat into the manifold
and secure the stem and seat with the stem
retainer
(Figure 123
4.
Ensure that the back seating O-ring and the ball
seat are aligned and seated into the end-cap
fitting
(Figure 123
5.
Install the end-cap fitting assembly onto the
manifold body until the flange of the end-cap
fitting touches the manifold body
and
Figure
124), 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
Note:
The valve stem should fit inside the ball
drive slot. If the valve stem does not fit, adjust
the position of the ball
