Counterbalance Valves Technical Information
Dual Counterbalance - Hydraulic Vent
VCB06-EN-DL
OPERATION
This is a dual counterbalance HIC, 6-size metric, hydraulically vented, internally-piloted, low leakage, with a nose to nose design. The VCB06-EN-DL allows free flow from the V ports 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. excavators.
