SELECTIVE CONTROL VALVE
The selective control valve is situated on
the rear-hand tractor side under the cab
and is delivered as two-section type.
Each section has four positions with a
floating position and controls two
pressure outlets (quick couplings)
marked:
"3", "4" section 1
"5", "6" section 2
The control levers of sections are located
in the cab on the fender of the right-hand
rear wheel.
The section of the selective control valve
that operates quick couplings "3“ and "4“
has - besides the floating position - also
locked both working (pressure) positions
with hydraulic securing 16
+1,5
MPa.
In addition, the outlet “4“ is equipped with
the non-return valve – utilisation for
connection of the working branch of
machine with increased requirement for
tightness – minimum implement drop for
instance during transport.
