The P74JA Series differential pressure controller is commonly used
on water systems to control a pressure differential between supply
and return lines. The controller’s SPDT floating action contacts
position a modulating valve operated by a motor-driven actuator. In a
typical application the valve is located in a bypass line around the
system pump.
