CP702-3
OPERATION
The CP702-3 is a 16-size, normally open, pilot-to-close, spring-biased
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.
