OPERATION

The HLEA10-CPC is a 10-size, high pressure, normally-closed,
pilot-to-close, spring biased dierential-sensing logic
element that includes an adjustable compensator feature. It
will modulate ow from 1 to 2 based on the spring control
pressure, inlet pressure at port 1, and pilot pressure at port 3.

APPLICATION

Common applications include load-sensing bypass compensator for a xed displacement
pump with single or multiple actuators as well as bypass-type pressure-compensated ow
control. Eective use of logic elements is a key to designing cost-eective circuits, and is
limited only by the imagination of the designer.
