15K, 20K Uni-Valve Service

Disassembly

1.  Remove the O-ring at each end of the valve 

(Figure 72). Discard the O-rings.

2.  Locate the slits in the two white backup rings 

and carefully remove the rings. Remove the 

companion O-rings, as well (Figure 73). Dis-

card the O-rings and backup rings.

Note: 

Note the orientation of the seals for 

installation.

3.  Use a small screwdriver to depress the spring 

retainer. Use another screwdriver to remove 

the retaining ring. Insert the blade under the 

slit and rotate the ring out of the groove. Use 

caution to prevent bending or distorting the 

ring (Figure 74).
