Pilot Operation Control Circuit ZAXIS ZX210-6, ZX210LC-6, ZX240N-6
Pressure oil (1 to 16) from the pilot valve are routed to the spools in the control valve and move the spools.
Pressure oil acts on the following selector valves when performing the following operations.
– When performing arm roll-in (4) operation, pressure oil moves the arm spool and shifts the selector valve spool of the arm rod anti-drift valve (e).
– When performing arm roll-out (3) operation, pressure oil shifts the selector valve spool of the arm bottom anti-drift valve (d).

– When performing boom lower (2) operation, pressure oil shifts the selector valve spool of the boom anti-drift valve (c). The divided pressure oil shifts the boom 1 spool and the boom 2 spool through the boom lower meter-in cut valve (b).

Air bleed circuit (a) is located in the upper of control valve and bleeds air automatically.
