Norgren R82R-2AK-RMN Reverse Flow Regulator - Excelon Plus Relieving
Part Number: R82R-2AK-RMN
Quick Summary
Norgren R82R-2AK-RMN reverse flow regulator is a compact, precise pressure control device for compressed air systems. Many automation lines suffer backflow, pressure drift, and actuator chatter, which this regulator helps prevent. It carries CE marking and is produced under ISO 9001-based quality processes to ensure reliability in demanding environments. This Excelon Plus model combines a lightweight 0.23 kg body with a push-to-lock adjusting knob, offering stable setpoints and easy recalibration in field or OEM installations. Designed for 1/4" PTF porting with a 0.3–10 bar outlet range and a 20 bar maximum inlet, it delivers predictable performance in automation and tooling applications.

Feature → Business Impact → Application: The reverse flow design provides backflow protection, reducing unintended actuator movement and system leaks, which lowers downtime in automated lines and packaging systems. Application: pneumatic circuits requiring dependable safety and stability. Feature → Business Impact → Application: Outlet pressure is adjustable from 0.3 to 10 bar via a knurled knob, enabling rapid tuning to match process changes without exhaustive rework. Application: line feeding, gripping, and consistent cylinder actuation in assembly cells. Feature → Business Impact → Application: Push-to-lock knob with tamper resistance preserves the set pressure in vibration-prone environments, decreasing recalibration frequency and labor costs. Application: robotic pick-and-place and CNC tooling interfaces. Feature → Business Impact → Application: Lightweight diecast aluminium body and compact envelope simplify integration, improve enclosure density, and reduce install time. Application: panel-mounted regulators in space-constrained panels. Feature → Business Impact → Application: Materials selection (acetal knob, nitrile elastomers) provides durable, chemical-resistant operation across typical factory air lines. Application: aggressive production environments and humidity-prone areas.

FAQs
Begin by ensuring the supply is within the 20 bar maximum inlet range. Connect the 1/4 inch PTF port to the upstream line and attach the gauge port (1/8 inch PTF) to your monitoring instrument if needed. Use standard pneumatic fittings and verify the orientation and tamper-resistant knob is accessible for adjustments. After installation, test for leaks at low pressure and gradually ramp to operating levels to confirm correct flow direction and relief function.
The outlet pressure can be adjusted from 0.3 to 10 bar using the knob. Begin at a conservative setting, then incrementally increase while observing the downstream actuator response. Confirm that the regulator relieves excess pressure and prevents backflow during backpressure events. Document your target setpoint for traceability and ensure the knob remains secure in operating conditions to avoid drift.
Yes, the regulator features a tamper-resistant push-to-lock knob designed to resist unintentional setpoint changes in vibration-prone zones. This makes it well-suited for automated equipment, conveyors, and robot cells where mechanical shock or continuous motion could otherwise affect stability. For best results, mount with appropriate supports and verify that the mounting surface is clean and free of debris before commissioning.
The R82R-2AK-RMN is CE-compliant and produced under robust quality management practices aligned with ISO 9001, ensuring consistent product performance and traceability. While passive components like regulators are typically tested for compliance rather than active safety certifications, these marks indicate suitability for European equipment and general industrial use in regulated environments.
The regulator reduces downtime through reliable backflow prevention and stable pressure, lowering actuator wear and process inconsistencies. Maintenance is typically limited to periodic outlet pressure verification and visual inspection for seals, especially in high-temperature or chemically aggressive environments. The easy-to-adjust knob and modular design minimize field service time, supporting a favorable total cost of ownership in OEM and maintenance contexts.
