Construction of relief valve
The valve casing contains two cartridge type relief valves that stop the regular and reverse
rotations of the hydraulic motor. The relief valves relieve high pressure at start or at stop of swing
motion and can control the relief pressure in two steps, high and low, in order to insure smooth
operation.

Function of relief valve
Figure illustrates how the pressure acting
on the relief valve is related to its rising
process. Here is given the function,
referring to the figure following page.
