Norgren R73G-2AK-RFN Pressure Regulator - Excelon Relieving
Part Number: R73G-2AK-RFN
Quick Summary
Norgren R73G-2AK-RFN is a general purpose pressure regulator for compressed air systems in automation and manufacturing. It helps you tackle downstream pressure fluctuations and dead-end risk by delivering stable, balanced control even as demand changes. Typical Excelon regulators carry CE compliance, and many designs support SIL-ready safety architectures; IP ratings vary by enclosure and installation—check the datasheet for specifics. The compact, inline or modular installation enables flexible retrofits with minimal piping changes. With a push-to-lock knob and tamper-resistant accessory, it reduces calibration drift and maintenance overhead. By matching 1/4 inch porting and a 0.3-4 bar output to standard plant air needs, you gain consistent performance and lower operating costs.

Feature → Balanced valve design provides stable downstream pressure, reducing actuator stall and cycle-time variability. Business Impact → Smoother motion control, tighter tolerances, and fewer recalibrations on high-speed pneumatic lines. Application → Ideal for pick-and-place robots, clamping stations, and general automation where consistent pressure improves cycle repeatability and product quality. Feature → In-line or modular installation enables flexible mounting with minimal piping changes. Business Impact → Reduces commissioning time and simplifies retrofits in existing machinery. Application → Suitable for retrofits in compact panels or on main line feeds, where space is limited and future expansion is anticipated. Feature → Relieving function protects downstream circuits during dead-end conditions. Business Impact → Improves safety, reduces risk of hose bursts, and simplifies system certification. Application → Helpful in remote lines and process zones where backpressure can occur. Feature → Push-to-lock adjusting knob with tamper-resistant accessory minimizes drift from unintentional changes. Business Impact → Maintains set pressure across shifts, lowering maintenance frequency. Application → Beneficial in environments with vibration or operator turnover. Feature → Durable materials (die-cast aluminium body, zinc bonnet, acetal knob, nitrile elastomer seals) deliver rugged performance in manufacturing plants. Business Impact → Long service life, resistance to oil-contaminated air and temperature swings. Application → Suitable for automotive, packaging, and food & beverage lines. Feature → Wide operating range -34 to 80 °C and maximum inlet 20 bar with 0.3–4 bar output ensures compatibility with common shop-air systems. Business Impact → Consistent performance across diverse environments and seasons. Application → Fits standard pneumatic circuits in modern factories.

FAQs
The R73G-2AK-RFN supports both inline and modular installation, enabling flexible mounting on main lines or within compact control panels. Its 1/4" PTF ports and gauge port simplify piping and integration with existing pneumatic circuits, reducing retrofit time and minimizing disruption to production lines.
Relieving regulation protects downstream components by reducing pressure when the system is dead-ended, preventing pressure spikes that can damage actuators and hoses. This improves safety, extends component life, and helps maintain consistent tool performance in dynamic production environments.
Yes. The R73G-2AK-RFN features a push-to-lock adjusting knob with tamper-resistant accessory options, helping prevent unintentional changes during operation and maintenance. This maintains set pressure, reduces calibration drift, and lowers the risk of inconsistent performance.
Operating temperature ranges from -34 to 80 °C, with a maximum inlet pressure of 20 bar and an outlet pressure range of 0.3 to 4 bar. It uses 1/4" PTF ports and provides a flow capacity of up to 60 dm3/s, making it compatible with standard shop-air systems.
Industries such as automotive, packaging, electronics assembly, and general manufacturing benefit from the Excelon R73G's reliable pressure control, modular installation, and robust materials. Applications include pneumatic actuators, clamps, and precision automation where stable regulation improves cycle times and product quality.
