Manual Extract

The process of moving the remote hydraulic control lever to the retract position initiates the shift of the main valve spool to the right, managed by a proportional solenoid pressure supply. This movement determines the flow rate to the retract port.

As the main valve spool shifts, it directs flow from the intermediate pressure area to the lower port and the left-hand side of the load check plunger. This results in the rightward movement of the plunger, unseating the load check pilot poppet, and relieving pressure on the spring side of the main poppet back to the tank. Consequently, this action unseats the main poppet, facilitating the return oil flow back to the inlet side of the filter base. The differential pressure between the raise port and the spring side of the main poppet aids in this unseating process.

Simultaneously, work pressure is communicated to the signal check through a center-drilled passage in the main valve spool, activating the signal pressure directed to the pump compensator to increase the PFC pump flow.
