OPERATION
The HLE10-OVC is a 10-size, normally open, vent-to-close, springbiased dierential-sensing logic element. 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
Common applications include: high-ow pressure reducing valve
when using a small relief valve (like CP208-1), or a proportional
relief valve (like PRV08-DAC) as a pilot element. Eective use of logic
elements is a key to designing cost-eective circuits, and is limited
only by the imagination of the designer.
