OPERATION
The CP702-2 is a 16-size, normally closed, vent-to-open, springbiased 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.
