Product Overview
The FESTO LRP-1/4-4 is a precision pneumatic pressure regulator engineered by Festo for accurate downstream pressure control in compressed air systems. As a member of the Festo LRP series, this regulator operates on a diaphragm-controlled, force-balance principle, delivering highly stable outlet pressure independent of fluctuating inlet pressure and varying flow demand. With a 1/4-inch port size and a 4 bar nominal output pressure range, the LRP-1/4-4 is designed for sensitive pneumatic applications where precise pressure regulation, repeatability, and minimal hysteresis are essential. It serves as a critical control component in pneumatic valve manifolds, actuator circuits, and process control loops across industrial automation environments.
