VCB06-EN-DL Counterbalance Valve
English Chinese (Simplified)

comatrol hydraulic cartridge valves




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.





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.
