Logic Elements Technical Information

Spool Type
HLE10-CPC

OPERATION

The HLE10-CPC is a 10-size, high pressure, normally-closed, pilot-to­close, spool-type, spring biased dierential-sensing logic element. 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
