OPERATION
The HLE10-OPO is a 10-size, high pressure, normally open, pilot-to-open,
spring-biased dierential-sensing logic element. It will modulate ow
from 2 to 1 based on the spring control pressure, inlet pressure at port
1, and outlet pressure at port 3. The HLE10-OPO technically replaces the
CP700-4L, but cavities are not interchangeable.
* Rated Pressure based on NFPA fatigue test standards (at 1 Million Cycles).

Common applications include: as a pre-compensator for proportional
directional control or ow controls, as well as a pressure control valve.
A common application for this valve is as a pressure compensator
when applied with a xed, or adjustable orice to create a
pressure-compensated ow control. This ensures that ow rate,
and resulting actuator speed is maintained regardless of pressure drop across the control orice. Eective use of logic
elements is a key to designing cost-eective circuits, and is limited only by the imagination of the designer.
