The integrated gauge and T-bar adjustment deliver immediate visibility and quick calibration, reducing commissioning time and enabling tighter process control. This translates to consistent downstream pressure, improved part accuracy, and lower scrap rates in high-volume packaging and automation lines. The relieving regulator design ensures safe venting during pressure regulation, helping protect downstream equipment and operators while maintaining stable output across load changes. Made with a diecast aluminium body, zinc-plated adjusting knob, and nitrile elastomer seals, the unit offers solid durability, corrosion resistance, and long service life in harsh factory environments. The 1/2" PTF inlet and 1/8" PTF gauge port support common pneumatic fittings, simplifying installation and service. With a compact footprint (74 mm L x 70 mm W x 186 mm H) and a weight of 0.59 kg, it fits tight spaces and supports quick mounting using standard brackets (such as Excelon Plus mounting kits). Accessory options include integrated gauges, general mounting brackets, neck brackets, and Quikclamp assemblies to speed up installation in control panels and machine frames. The unit is compatible with Excelon Plus strain relief and elastomer service kits, helping reduce maintenance downtime and spare-part inventory while preserving performance integrity over time.

FAQs
The R84G-4AT-RSG supports standard Excelon Plus mounting configurations. Optional brackets and fasteners from the Excelon Plus range, including general mounting brackets (840024-50KIT) and neck mounting brackets with panel nuts (840068-51KIT), simplify panel and frame installations. Quikclamp options (840014-51KIT, 840014-52KIT) speed up clamp-based installations, reducing setup time and ensuring vibration resistance in dynamic industrial environments.
Key specs include a 1/2" PTF port, gauge port 1/8" PTF, outlet pressure adjustment from 0.7 to 17 bar (10 to 247 psi), a maximum inlet pressure of 20 bar, and a flow of 125 dm3/sec (265 scfm). This combination supports versatile control in general-purpose compressed air applications while maintaining responsive regulation under load changes.
Yes, the unit is a relieving regulator. This means excess downstream pressure is vented to atmosphere when required, protecting downstream components and ensuring safe venting during pressure fluctuations. This feature helps prevent over-pressurization in sensitive tools and preserves system stability in production lines.
Compatible accessories include the Excelon Plus integrated gauge kit (840073-02KIT), Excelon Plus general mounting bracket (840024-50KIT), neck mounting bracket with panel nut (840068-51KIT), Quikclamp kits (840014-51KIT and 840014-52KIT), and the Excelon Plus elastomer service kit FRLB84-KIT. These items streamline installation, calibration, and maintenance for reliable long-term operation.
Prioritize correct port orientation (1/2" PTF inlet and 1/8" gauge port), ensure flush-mounted gauge accessibility, and select appropriate mounting hardware from the Excelon Plus family. Operating temperature is -20 to 65°C, and the compact footprint supports tight enclosures. Using the recommended mounting brackets and clamps reduces vibration and misalignment, while the integrated gauge minimizes external instrumentation and simplifies field diagnostics.
