DCB10-MC

OPERATION

Dual counterbalance HIC, 10-size, hydraulic vent with make-up checks. This is an
internally piloted, low leakage assembly. The DCB10-MC uses two CB10-HV cartridges
and four CV10-NP check valves, allowing 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. Connect the T port to a tank line
to allow for make-up ow into the circuit.

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.
When make-up feature is needed, connect ‘T’ port to reservoir or charge system. This allows the load to be smoothly
controlled with minimum energy loss. If load tries to run ahead of pump, pilot pressure will decrease and the relief
section will throttle or close to prevent runaway. The T port is also useful in cylinder applications where directional
valves (specically proportional valves) are sensitive to ow intensication of powering the rod side. The DCB10-MC
diverts ow directly to tank and bypasses the directional valve. This HIC technically replaces the 1EEC11-01.
