Cylinder Control Systems

40-B. Bucher L.8S - Electric Control/Cable

FIXED DISPLACEMENT VALVE END CAP

When the tractor is started and the main spool in the 5 sections of the control valve are in the neutral

determines the pump pressure. (Pump pressure at the neutral position will be equal to standby

pressure).

When one or more of the main spools are activated, the load pressure is fed through the shuttle (or

load sense) valve circuit to the spring chamber behind the pressure bypass adjustment spool. This

needed.

The pilot reducing valve maintains standby (pilot) oil pressure to the proportional control system (200 to

250 psi)
