Packing Refuse (2)
Hydraulic Sequence
While the carrier and packer panels are moving up, compacting
refuse against the pushout panel,
pressure is building in the case end of the carrier cylinders. This pressure is also building in a pilot line
from the carrier valve section to the FCV (Front Control Valve) pushout section. When this pressure
reaches 1800
PSI
(124
BAR), a relief (resistance) cartridge opens in the FCV (Front Control Valve)
pushout section, allowing some case end pressure from the telescopic pushout cylinder to return to
tank. This allows the pushout panel to come
forward slightly.
