Working Principle
A11VO60DRSP, LDRSP, A11VO60HD1D EP2D and A11VLO190HD1D EP2D, EP6Z, EP2S, 190LR3DS Control Valve cooperate closely inside the hydraulic system. The matched control valve adjusts the swashplate angle of the Hydraulic piston pump, realizing stepless flow output. Different control options deliver multiple control logics including pressure limiting, load sensing and electric proportional control. The 190LR3DS Control Valve responds quickly to system signals, keeps the hydraulic pump running stably under fluctuating loads, and guarantees overall system efficiency. These Hydraulic Pump Spare Parts can be used for pump overhaul and direct equipment replacement.
