Unloading Valve E307D E307F Excavator Hydraulic Components
Mechanical Components
Functions:
1. Unload the hydraulic cylinder: When the unloading valve is
opened, the hydraulic oil is released from the cylinder through the
unloading valve to the hydraulic tank, so that the hydraulic
pressure in the cylinder is reduced to zero, and the load carried
by the hydraulic cylinder is removed.
2. Maintain zero position: After unloading, the hydraulic cylinder
will remain in the zero position under no load.
3. Energy saving: After unloading, there is no load in the
cylinder, saving the energy for hydraulic oil.
4. Reduce wear: After reducing the load, the wear of the components
in the hydraulic cylinder is reduced.
5. Prevent hydraulic lock: Prevent hydraulic oil leakage caused by
hydraulic lock.
