2.3 Valve Assembly

3” and 4”

To assemble a ball valve:

1.  Place the lower packing ring (11) on the valve stem (4) and slide the stem into the stem 
 

hole in the upper body of the valve.

2.  Press the upper packing rings (10) onto the stem (4) until it is seated against the base 
 

of the body.

3.  Press the packing retainer (9) onto the stem (4) until it is seated against the upper 
 

packing ring (10).

4.  Turn the stem (4) until the flat surfaces are parallel to the port centerline.

5.  Place a ball seat (8) inside one end of the valve body (1) so that the tapered side of the 
 

seat faces inward and the other side lies flush against the outer surface of the valve 

 

body.

6.  Seat the ball (3) inside the valve so that the stem base is seated inside the bore of the 
 

ball.

7.  Turn the stem 90° so that the valve is in the open position.  This keeps the ball from falling out of the valve.

8.  Place the other ball seat (8) inside the end of the valve body (1) so that the tapered side of the seat faces inward and the 
 

other side lies flush against the outer surface of the valve body.
