Manifold Repair (See Page 10. )
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 8.
Note: Repair kits are available for the manifold. Parts
included in the kits are indicated with a †, for example
(9†) See page 11.
1. Relieve the Pressure.
2. Remove the twelve socket-head screws (2) to
separate the two valve housings (8) from the
manifold housing (7). Remove all parts from the
housings.
3. Clean all parts thoroughly in a compatible solvent.
Use a soft bristle brush to clean the manifold
passageways.
4. Install the two check valve assemblies (9†) and
valve seats (6†) in the manifold housing (7).
5. Install the needle valve (12), back-up ring (4**),
and seal (3†) in each of the valve housings (8).
6. Install six socket-head screws (2) through one
valve housing (8) and into the manifold housing
(7), so the distance between the housings is
0.060 in. (1.5 mm).
7. Tighten the needle valve slightly, so that the
tapered end centers in the seat (6) and holds its
position.
8. Turn the six socket screws (2) oppositely and
evenly to 60–70 in-lbs (6.7–7.9 NSm). Back off the
needle valve (12) slightly.
9. Repeat step 8 as the torque will relax.
CAUTION
Be sure to tighten the six socket screws (2) evenly.
The upper four screws, which surround the needle
valve assembly (12), are critical in ensuring that the
needle seats properly. If the bottom two screws are
over-tightened, they will throw off the alignment.
10. Repeat the procedure from step 9 on the other
valve housing (8).
Ball Valve Repair (See Page 10.)
Note: Repair Kit 217560 is available for the ball valves.
Parts included in the kit are indicated with an asterisk,
for example (18*). See page 11.
When reassembling a ball valve (13 or 24), install the
ball (18* or 29*) so that the round hole aligns with the
main passageway of the valve body and the square
hole aligns with the stem (21 or 32) passageway.
