Product Overview
The FESTO LR-D-MINI (Part No. 8002390) is a precision pneumatic pressure regulator from the FESTO D-series family, engineered to maintain a stable, user-defined downstream working pressure regardless of fluctuations in upstream supply pressure or changes in flow demand. As a directly actuated diaphragm-type regulator, it operates on a force-balance principle: an adjustable spring acts against a rolling diaphragm to position the valve poppet, delivering accurate secondary pressure regulation with minimal hysteresis. With its compact Mini form factor, the LR-D-MINI is designed for space-constrained pneumatic control panels and integrates seamlessly into FESTO service units, FRL combinations, and modular air preparation systems. It serves as a critical control component in industrial automation, ensuring consistent actuator force, repeatable process behavior, and protection of downstream pneumatic components from over-pressurization.
