For EUT-2 and EWT-2 valves, use care to avoid
damaging the seat ring seal ring and cage seating
surfaces while handling the heavy parts. To help
insert the cage or assembly into the valve, lubricate
the outside diameter of the seat ring seal ring with
lithium grease.
3. Slide the valve plug (key 2) and stem assembly
into the cage.
Figure 8. Typical Fisher EUD Valve
For valves with a seal ring, make sure the valve plug
seal ring (key 28) is evenly engaged in the entrance
chamfer at the top of the cage or cage assembly to
avoid damaging the ring.
For valves with piston rings, make sure the rings are
fully engaged into the piston ring groove and flush
with the outside diameter of the plug.
4. Install the bonnet gasket (key 10).
