HLEA10-OPO High Pressure Logic Elements
English Chinese (Simplified)

comatrol hydraulic cartridge valves


The HLEA10-OPO is a 10-size, high pressure, normally open, pilot-to-open, spring-biased differential-sensing

logic element that includes an adjustable compensator feature.

It will modulate flow from 2 to 1 based on the spring control pressure, inlet pressure at port 1, and pilot pressure at port 3.



The adjustability of the HLEA10 allows the operator to change the compensator setting

of the logic element, ranging from 2.75 to 15.2 bar (40 to 220 psi).

This is especially helpful when fine tuning the applications, providing flexibility to the operator and allowing for machine optimization.
