Operation

 

The VCB12-CN-DL is a dual counterbalance HIC, 12-size metric, nose to nose design with atmoshperic vent. This catalog HIC 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

Atmospherically vented valves 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.
