5.8 Rebuilding the Static Valve
Leaking from the source needle into the collection vessel during the static cycle
indicates that the static valve is worn and must be rebuilt. The rebuild procedure
consists of replacing a few parts (an O-ring, a filter, and two seals) and then
cleaning the inside of the valve body.
Before proceeding, check that the following kits are on hand. The kits contain the
replacement parts and special tools required to rebuild the valve.
•
Order a Static Valve Repair Kit (P/N 068115) each time the valve requires
rebuilding.
•
Order a Static Valve Tool Kit (P/N 068116) only the first time the valve
requires rebuilding.
Figure 5-19 illustrates each tool.
