Norgren R73G-3GT-NSN Pressure Regulator - G3/8
Part Number: R73G-3GT-NSN
Quick Summary
Norgren R73G-3GT-NSN is a precision pressure regulator for compressed air systems, delivering stable outlet pressure for automation lines. Fluctuating pressure and slow adjustment can disrupt actuators and hinder precise process control. In the Excelon family you can expect CE compliance, IP-rated variants, and SIL-ready configurations to support safety and reliability in critical applications. Inline installation or modular mounting, plus a push-to-lock, tamper-resistant knob and balanced valve design, translate to faster setup, repeatable results, and lower operating costs.

Balanced valve design provides stable outlet pressure across changing loads, reducing actuator overshoot and improving cycle stability in automation lines. This translates to tighter process control, faster startup, and lower wear on downstream cylinders. In practice, engineers see improved repeatability in pick-and-place and assembly applications. Inline G3/8 porting and modular installation support compact manifolds, cutting installation time and simplifying future expansions. The 0.7–17 bar outlet range offers flexibility to drive various actuators, while a 20 bar maximum inlet tolerates supply transients without overpressure. The non-relieving design keeps downstream pressure stable, essential for sensitive tools. Push-to-lock adjusting knob with tamper-resistant accessory protects setpoints in busy plants, and zinc-plated knobs combine security with serviceability. Durable diecast aluminum body, zinc bonnet, and nitrile elastomer seals deliver long life in challenging factory environments. Compatibility with Rc1/8 gauge port and Excelon 73/74 accessories enables easy integration into existing lines and modular systems, reducing spare parts and speeding future upgrades. In high-mix environments, inline regulators like R73G-3GT-NSN streamline layout and improve overall line reliability.

FAQs
This regulator supports inline mounting with a G3/8 port and an Rc1/8 gauge port for pressure monitoring. Its compact diecast aluminum body and modular Excelon accessories enable easy integration into tight control panels or compact manifolds, reducing assembly time and enabling scalable layouts.
The outlet pressure is adjustable from 0.7 to 17 bar (10 to 247 psi), with a maximum inlet pressure of 20 bar. This range accommodates a broad spectrum of pneumatic actuators while maintaining stable downstream pressure for reliable performance.
Yes. The Excelon design emphasizes a balanced valve and tamper-resistant adjustment, providing repeatable pressure control essential for precision automation, robotics, and high-volume packaging where consistent cylinder force and cycle timing are critical.
Certification specifics for this exact model aren’t listed here. Verify datasheet and supplier documentation for CE compliance, IP protection level, and any SIL-ready configurations relevant to your safety and regulatory requirements.
The push-to-lock knob minimizes accidental setpoint changes, reducing drift and maintenance needs. Durable materials (diecast aluminum, zinc components, nitrile seals) and a non-relieving design contribute to stable operation, longer service intervals, and lower total cost of ownership in busy industrial environments.
