Counterbalance Valves Technical Information

Dual Counterbalance - Hydraulic Vent
DCB20-HV

OPERATION

DCB20-HV: Dual counterbalance HIC, 20-size, hydraulic vent. This HIC
is low leakage and internally piloted. The DCB20-HV uses 2 CB20-HV
20-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

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.
