Auxiliary hydraulic spool valves
Auxiliary spool valves are used to control hydraulically operated external implements.
The controls consist in 2 levers for a 4-way valve, or 3 levers for a 6-way valve, or 4 levers for an 8-way valve. The
levers are located on the driver’s right hand side.
Auxiliary hydraulic spool valves:
— 4-way
•
2 way double acting
•
2 way double acting convertible to single acting, with spool detent
— 6-way
•
2 way double acting convertible to single acting, with kickout
•
2 way double acting convertible to single acting, with spool detent
•
2 way double acting with float position
— 8-way with flow divider
•
2 way double acting convertible to single acting, with kickout
•
2 way double acting convertible to single acting, with spool detent
•
2 way double acting with float position
•
2 way double acting
NB: with the auxiliary spool valve in use (unless a Flow Divider is incorporated), the operation of the hydraulic lift system
remains inhibited (except in FLOAT position).
Important: the lever should be recentred to the neutral position as soon as the external actuator has reached its stroke
limit, to ensure that the hydraulic circuit does not remain pressurized any longer than strictly necessary; prolonged
pressure will result ultimately in the hydraulic system being subjected to hazardous levels of stress.
Auxiliary spool valves levers must always be in the neutral position when external services are not in use.
