Operation

 

The VCB12-EN-DL is a dual counterbalance HIC, 12-size metric, hydraulically vented, internally-piloted, low leakage, with a nose to nose design. 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.
