CB10-HV Counterbalance Valve
English Chinese (Simplified)

comatrol hydraulic cartridge valves





CB10-HV : Counterbalance valve, 10-size, hydraulic vent. This valve is 3-ported, externally piloted and low leakage. The check section allows free flow from the directional valve (port 2) to the load (port 1), while normally blocking flow from port 1 to port 2. Reverse flow is blocked until pilot pressure is applied at port 3. When the load pressure at port 1 rises above the pressure setting, the intergral relief valve is activated and pressure is relieved from port 1 to port 2.





Single counterbalance valves are normally used when the load is unidirectional, such as aerial lifts, cranes, or winches. In load holding applications, they can be used as hose-break valves when installed near or within an actuator. Dual valves can be used for controlling loads bi-directionally in motor applications, or for cylinders going over center.
