Theory of Operation
BOOM REGENERATIVE VALVE OPERATION
head end the return oil pushes the boom regenerative
The function of boom regenerative valve (H) during
valve poppet (C) open and flows to the rod end.
boom down operation is to combine the return oil flow
Return oil not used flows through the boom
from head end of boom cylinders (G) with the pump
regenerative valve orifice (D) to the return passage.
The boom I neutral passage check valve (E) prevents
During boom down operation, if pump supply oil
back flow through the control valve.
pressure is lower than the return oil pressure from the
