Dual Counterbalance - Atmospheric Vent
DCB10-AV
OPERATION
DCB10-AV : Dual counterbalance HIC, 10-size, atmopheric vent.
This HIC is low leakage and internally piloted. The DCB10-AV uses 2
CB10-AV 10-size cartridges and allows free ow from the V port to the
C ports and blocks ow in the reverse direction until the relief setting
is reached, or until adequate pilot pressure has been applied to the
opposite V port.
APPLICATIONS
Atmospheric vented valves are applied when it is not practical to
connect a separate vent line to the tank. Use dual counterbalance
HIC’s for controlling loads in bidirectional motion such as wheel motor
applications or for cylinders going over center. They are also suitable
for use on the boom and dipper cylinder on an excavator.
