PR550X Series G1/4 compact low (7 bar) and high pressure (10 bar) regulators with flows to 570 l/min.
The 550X series miniature proportional regulator is an electronic pressure regulator that converts a variable signal (current or voltage) to a proportional pneumatic output. It’s compact housing, accessible ports and easy adjustments provide an ideal answer to applications that are space-constrained. This economical instrument provides precision air pressure regulation to actuators, valves, positioners and other final control elements. An integral volume booster provides high flow capacity, increasing control speed in critical applications.
