2.  Orient the Bore Seal plug seal for correct sealing
action based on the process fluid flow direction
through the valve.

D

The open interior of the Bore Seal plug seal

must face up in a valve with flow-up construction 
(figure 5).

D

The open interior of the Bore Seal plug seal

must face down in a valve with flow-down
construction (figure 5).

Note

An installation tool must be used to
properly position the Bore Seal plug
seal on the valve plug. A tool is
available as a spare part from Emerson
Process Management or a tool could

be manufactured following the
dimensions given in figure 6.

3.  Place the Bore Seal plug seal over the top of the
valve plug and press the Bore Seal plug seal onto
the plug using the Bore Seal installation tool.
Carefully press the Bore Seal plug seal onto the plug
until the installation tool contacts the horizontal
reference surface of the valve plug (figure 8).

4.  Apply a suitable high-temperature lubricant to the
threads on the plug. Then, place the Bore Seal
retainer onto the plug and tighten the retainer using
an appropriate tool such as a strap wrench.

5.  Using an appropriate tool such as a center
punch, stake the threads on top of the plug in one
place (figure 7) to secure the Bore Seal retainer.

6.  Install the new plug/retainer assembly with Bore
Seal plug seal on the new stem following the
