) from Cylinder (

25

).

25. Remove O-Ring (

12

) , Stop (

26

), and Ball (

27

) from 

the Valve Body.

Clean and Inspect

  1. Clean all metal parts in cleaning solvent. The solvent 

should be environmentally safe.

  2. Inspect all parts for wear and/or damage.

  5. Closely inspect the mating surfaces of all check valve 

components for any imperfections. Ensure a smooth 
and clean contact is obtained when assembled.

EXAMPLE

:  Place  Ball  (

27

)  into  Valve

Body (

28

). Fill the Valve Body with solvent.

Make sure no leakage occurs.
