Hydrualic Diagnosis

Control valve in Extend (splitting)

• The pump drives hydraulic fluid to the control valve.

• The spool in the control valve directs pressurized fluid to the base end of the cylinder.

• The pressurized fluid forces the piston up the bore of the cylinder.

• As the piston moves up the bore, it displaces fluid that is on the ram side of the piston.

• The spool in the control valve also connects ports joining the ram end of the cylinder to the reservoir.

• This allows displaced fluid to return to the reservoir.
