4.  Slip bearings (4)(5) onto the plug (6) stub 

shafts.

NOTE:

 Bearings (4) (5) are not the same length. 

The shorter bear ing (5) fits the plug (6) stub shaft 
that has the tongue end. See Figure 5.

5.  Rotate plug (6) to the closed position. Ensure 

that the plug (6) is fully pulled into the 
me chan i cal stop (5) on the cage (2). See Figure 
7. Ensure that the closing torque is nil; i.e. 
actuator assembly (AA) linkage is “loose” or 
“slack”.

6.  Insert the cage/plug subassembly (2)(4)(5)(6) 

into the body (1). On 1-1/2" and 2" sizes with 
lo-noise inserts or abra sion sleeve, make sure 
these pieces and the cage (2) slip together 
on the back of the cage (2). Make sure the 
tongue on the plug (6) stub shaft and the 
groove in the stem sub as sem bly (7) mate 
to geth er. Check by look ing in through the 
back-end of the body (1) or by ad just ing the 
supply pres sure to the ac tu a tor within limits 
of bench range as spec i fied on name plate 
(21), watch ing for plug (6) move ment as stem 
sub as sem bly (7) ro tates.

2.  If at the body assembly (BA) level, ensure 

that the stem sub as sem bly (7) is pulled back 
into the bonnet of the body (1) so that the 
stem (7) is in contact with the retainer sleeve 
sub as sem bly (8).

3.  Place plug (6) into cage (2). The ori en ta tion 

must be such that the short stub shaft of the 
plug (6) with the ma chined tongue extends 
through the flat side of the cage (2) toward 
the stem (7). The plug (6) must be rotated 
135° to 180° open before the plug (6) stub 
shafts will slip into the cage's (2) bearing (4)
(5) slots.  See figures 4 and 5.
