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 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

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.
