(2) Two check valves are used to prevent pressure oil backflow.
The specifiions and functions of the two check valves are the same. Low pressure valves and high pressure valves are used for pressure control. The pressure is controlled at 1.5MPa and 63, respectively
MPa. The two steel balls at the oil inlet are check valves. After the work is completed, loosen the unloading valve and the pressure oil flow back to the oil storage pipe to complete the unloading work.
(3) Handle part:
