Dual Counterbalance - Hydraulic Vent
VCB12-EN-DL
OPERATION
The VCB12-EN-DL is a dual counterbalance HIC, 12-size
metric, hydraulically vented, internally-piloted, low leakage,
with a nose to nose design. This catalog HIC allows free
ow from the V ports 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
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.
