Counterbalance Valves Technical Information
Dual Counterbalance - Atmospheric Vent
VCB06-CN-DL
OPERATION
The VCB06-CN-DL is a dual counterbalance HIC, 6-size
metric, nose to nose design with atmoshperic vent. This
catalog HIC allows free ow from the V ports 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
Atmospherically vented HIC’s are applied when it is not practical to connect a separate vent line to the tank. Use dual
counterbalance HIC’s for controlling loads in bidirectional motion such as wheel motor applications or for cylinders
going over center.
