Dual Counterbalance - Hydraulic Vent
DCB10-HV
OPERATION
DCB10-HV: Dual counterbalance HIC, 10-size, hydraulic vent. This is an
internally piloted, low leakage assembly. The DCB10-HV uses 2 CB10-HV
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
Dual counterbalance HIC’s are used 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.
