Spool Type

CP702-3

OPERATION

The CP702-3 is a 16-size, normally open, pilot-to-close, spring-biased differential-sensing logic element. It will modulate flow 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-flow pressure reducing valve when using a small relief valve (like CP208-1), or a proportional relief valve (like PRV08-DAC) as a pilot element. Effective use of logic elements is a key to designing cost-effective circuits, and is limited only by the imagination of the designer.
