Operation

 

This dual counterbalance, internally piloted catalog HIC is a low leakage assembly with hydraulic vent. This HIC uses 2 CP441-1 12-size cartridges and allows free flow from the V port to the C ports and blocks flow 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.
