LOOP FLUSHING BLOCK
English Chinese (Simplified)

comatrol hydraulic cartridge valves

LFB12r

 

OPERATION & APPLICATION

The Loop Flushing Block allows oil to drain from the power transmission loop to other oil treatment components. The low pressure side of the circuit is directed to the relief valve, which is then drained out of the transmission loop.

 

This HIC is typically used in closed loop circuits to assist in the process of removing contamination and cooling oil. Hydrostatic systems with sustained operation and continuous pressure will benefi t from a loop fl ushing circuit.

 

To confi gure the LFB12, determine the charge pump pressure and desired fl ushing fl ow. Working up from the desired fl ow, select the orifi ce size with a pressure rise that, when added to one of the available relief settings (in the ordering information section), meets the charge pump pressure.
