Spool Type
HLEA10-CVO
OPERATION
The HLEA10-CVO is a 10-size, high pressure, normally
closed, vent-to-open, spring-biased dierential-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: pump unloading, pilot-operated relief valve (mechanical or proportional),
sequence valve and selector circuit. 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
