Feature → Business Impact → Application: The Excelon Plus platform uses a compact diecast aluminium body and a knurled, push-to-lock adjustment knob to minimize misadjustments on the shop floor, reducing maintenance time and calibration drift. This directly improves line uptime on automated packaging and machining cells, where quick pressure tweaks are often required for tool changes. Feature → Business Impact → Application: G1/2 port size with Rc1/8 gauge port delivers broad compatibility with standard pneumatic fittings and inline gauges, enabling faster installation and easier diagnostics in today’s modular automation cells. Feature → Business Impact → Application: The 0.3–10 bar outlet range and 20 bar maximum inlet pressure provide precise, adaptable control for varying process loads, lowering energy use and reducing pneumatic waste on conveyors and end-of-line equipment. Feature → Business Impact → Application: Relieving operation enhances safety by venting excess pressure predictably, helping plants meet internal safety policies and regulatory expectations in high-cycle environments. Feature → Business Impact → Application: A tamper-resistant knob and durable elastomer seals minimize accidental setting changes and leaks, supporting long-term reliability in harsh factory conditions. Feature → Business Impact → Application: Integrated gauge option (RF-mounted) accelerates validation in commissioning and maintenance audits, while the modular accessory ecosystem (mounting brackets, panels, and service kits) simplifies retrofit and expansion in evolving lines.

FAQs

Install the regulator using the G1/2 port with a compatible compression fitting, connect the Rc1/8 gauge port for monitoring, and orient the device so the gauge is visible. Use the recommended mounting brackets (such as Excelon Plus general mounting) for panel or wall installation to ensure stability and easy access during adjustments.
The R84G-4GK-RMG offers an adjustable outlet range from 0.3 to 10 bar (approximately 4 to 145 psi). This enables precise regulation for diverse actuation needs, from delicate tooling to high-flow conveyor sections.
Yes. Its compact form factor, integrated gauge option, and 125 dm3/sec flow make it well-suited for dense packaging lines where space is at a premium and quick, verifiable pressure adjustments are required.
The product data specifies CE-compliant construction. For detailed safety and performance certifications (such as SIL readiness or IP ratings), please consult the datasheet or contact the manufacturer, as exact ratings depend on installation and system integration.
Several accessories support installation and service, including Excelon Plus Mounting Brackets, Integrated Gauge kits (10 bar), and elastomer service kits (FRLB84-KIT). These items facilitate retrofits, panel mounting, and ongoing maintenance to extend regulator life.
