Product Overview
The FESTO LR-D-MIDI (Part No. 8002287) is a precision pneumatic pressure regulator from Festo’s D-series family of service units, engineered to deliver stable, repeatable downstream pressure regulation in compressed air systems. As a diaphragm-type pressure regulating valve, it reduces fluctuating primary (inlet) pressure to a constant, adjustable secondary (outlet) pressure, protecting downstream pneumatic actuators, valves, and instrumentation from pressure surges and fluctuations. The LR-D-MIDI is a pilot-operated regulator with a rolling diaphragm and balanced valve poppet, offering high flow capacity, minimal pressure hysteresis, and excellent regulation accuracy across its full adjustment range. Its MIDI size (D-series, size 2) body is designed for inline mounting within Festo service unit combinations or as a standalone regulator, making it a core component in industrial compressed air preparation and control circuits.

Engineering Features & Advantages
- Precision Performance: Pilot-operated diaphragm design maintains constant outlet pressure with minimal droop and hysteresis, ensuring stable actuation of downstream pneumatic components even under varying flow demand.
- High Flow Capacity: The MIDI-size body provides generous flow cross-sections, minimizing pressure loss and supporting the air consumption requirements of medium-to-large pneumatic systems.
- Lockable Adjustment: Rotary adjustment knob with locking feature prevents unauthorized or vibration-induced changes to the set pressure, safeguarding process consistency.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with robust diaphragm and valve poppet construction resistant to wear and contamination.
- Direct Fit Replacement: Precision-manufactured to original FESTO specifications for direct replacement, minimising downtime and eliminating fitment issues.
