Reassembly of a control valve without a position indicator
Procedure
1. Place the cylinder in an upright position with the ports on the bottom. Lubricate the
inside of the cylinder wall with a suitable lubricant.
2. Insert the O-ring into the groove inside the bottom of the cylinder. This will require
some effort.
3. Insert the seat ring into the cylinder; placing it on top of the O-ring.
4. Using the piston as your tool, place it nose end down into the cylinder on top of the
seat ring. Using a hammer handle or similar device, press down on the piston to
force the seat ring into position against the lip in the cylinder.
5. Remove the piston from the cylinder.
