Feature: Push-to-lock adjusting knob with tamper-resistant feature → Business Impact: Reduces risk of unintentional re‑setting, ensuring stable downstream pressure and fewer process interruptions → Application: Ideal for high-speed packaging and robotics lines where vibration can cause drift. Feature: Relieving, reverse flow regulation → Business Impact: Safe venting and controlled pressure relief protects sensitive downstream components and tooling → Application: Enclosed automation cells and blow-off stations requiring controlled exhaust. Feature: Excelon Plus modular system and reduced weight/size → Business Impact: Easier retrofit and expansion, lower mounting loads, and simplified integration with other valves and regulators → Application: Retrofit projects in existing plants and new assemblies with limited space. Feature: Durable materials (diecast aluminium body, acetal knob, POM bonnet, nitrile elastomers) → Business Impact: Long service life, resistance to common compressible air contaminants, and predictable performance → Application: Harsh factory environments where reliability matters. Feature: Defined medium, operating temp, and pressure ranges → Business Impact: Wide operating envelope reduces need for multiple parts and supports standardized configurations → Application: Versatile for varied production lines; compatible with 0.3–4 bar output and up to 20 bar inlet in compressed air systems. Feature: Porting and gauge integration (G3/8 port, Rc1/8 gauge port) → Business Impact: Simplified piping and monitoring, faster commissioning and easier on-site adjustments → Application: New installations and upgrades requiring straightforward connectivity. End-to-end, these capabilities enable a predictable, compliant pneumatic supply with lower lifecycle cost and faster ROI.

FAQs
Begin by ensuring supply pressure is within the 20 bar maximum inlet rating and confirm the G3/8 port connections match your manifold. Mount the regulator securely, then attach the Rc1/8 gauge port to your pressure monitoring line. Use the push-to-lock knob to set the desired outlet pressure between 0.3 and 4 bar, and verify the relieving function is active. For retrofit projects, integrate with other Excelon Plus modules in a modular stack to minimize footprint and simplify maintenance.
The R82R-3GK-RFN provides an adjustable outlet pressure of 0.3 to 4 bar (4 to 58 psi) and supports a maximum inlet pressure of 20 bar. The regulator accommodates flow up to 31 dm3/s (66 scfm) and operates effectively in temperatures from -20 to 65 °C, making it suitable for most standard factory air lines.
Yes. The Excelon Plus R82R-3GK-RFN is designed for reliable, continuous operation in automated environments. Its reliving design, tamper-resistant knob, and durable diecast aluminium body help maintain a stable setpoint under vibration and long cycle times. The 0.3–4 bar output range covers common dispensing and tooling needs in packaging and assembly lines.
Product data packages typically include CAD files, a datasheet, and an installation guide. Certification specifics such as CE marking or SIL/IP ratings vary by market and regulatory requirements. For your region, consult the local compliance team and the supplier’s documentation to confirm exact standards and safety approvals for your application.
Maximize ROI by leveraging the tamper-resistant push-to-lock knob to maintain setpoints, reducing drift and operational downtime. The compact Excelon Plus modular design simplifies expansion or retrofits, cutting installation time and spare parts inventory. Durable materials and a broad operating envelope lower maintenance costs and support longer service life in demanding environments.
