HYDAC counterbalance valves are directacting poppet valves with integrated check valve which enable smooth action of loads if there are retracting and extending loads. In load-holding applications, it can be used as a hose-break valve.
To raise a load, flow is permitted from pump port 2 to load port 1 via the built-in check valve.
To hold the load, the check valve piston is pressed against its seat by the load pressure at port 1 and seals leakage-free (control port 3 must be unpressurized!).
To lower the load, pressure is applied to port 3 which controls the valve.
Therefore the load cannot speed ahead because the load flow rate is controlled at the metering edge of the control piston according to the load's inlet pressure.
A limitation of the load pressure is alos included - here the load pressure at port 1 acts on a ring surface against the force of the adjustment spring. When the spring force is exceeded, the control piston moves away from the check valve piston, and this opens the flow path from port 1 to 2.
