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 (
and
).
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 (
and
3.
Install the valve stem and seat into the manifold
and secure the stem and seat with the stem
retainer (
and
).
4.
Ensure that the back seating O-ring and the ball
seat are aligned and seated into the end-cap
fitting (
and
5.
Install the end-cap fitting assembly onto the
manifold body until the flange of the end-cap
fitting touches the manifold body (
and
), 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 (

7.
Turn the valve stem assembly so that the valve
is closed (
8.
Repeat steps
and
for the other end-cap
fitting assembly.
Installing the Rate Control
Manifold Valve
1.
Align a gasket between the flanges of the rate
control valve manifold and the pressure filter
head (
Note:
If needed, loosen the mounting hardware
for the pressure filter head as needed to provide
clearance.
