OPERATION
OPERATION
The HLEA10-OPO is a 10-size, high pressure, normally open,
pilot-to-open, spring-biased dierential-sensing logic
element that includes an adjustable compensator feature. It
will modulate ow from 2 to 1 based on the spring control
pressure, outlet pressure at port 1, and pilot pressure at port 3.
APPLICATION
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 ne tuning the applications,
providing exibility to the operator and allowing for machine optimization.
