RELIEF VALVE B
RELIEF VALVE B
During traveling operation, RA port pressure goes up and RB port pressure goes down.
Thus RA port pressure oil flows into chamber 3, and pushes plunger to the left with a high pressure
and the power of the spring.

RELIEF VALVE B
When it stops or operates reversely, RA port pressure is decreased and RB port pressure suddenly
goes up by the inertia of the machine heavy structure.
Relief valve B operates as the same order as relief valve A, and maintains the set pressure by
releasing the high pressure of RB port to RA port.
