OPERATION
The CP701-2 is a 12-size, normally closed, vent-to-open, spring-biased
dierential-sensing logic element. 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.
Eective use of logic elements is a key to designing cost-eective circuits,
and is limited only by the imagination of the designer.
