Danfoss HLE10-CPC Technical Information
Logic Elements Technical Information
Spool Type
HLE10-CPC
OPERATION
The HLE10-CPC is a 10-size, high pressure, normally-closed, pilot-to- close, spool-type, spring biased differential-sensing logic element. It will modulate flow 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 fixed displacement pump with single or multiple actuators
as well as bypass-type pressure-compensated flow control. Effective use of logic elements is a key to designing cost-effective circuits, and is limited only by the imagination of the designer
