Feature → Business Impact → Application: The compact, lightweight diecast aluminium body combined with a 186 mm height and 74 mm length saves panel space and reduces instrument weight, enabling easy integration into compact junctions or automated cabinets. This translates to lower installation costs and quicker retrofits in existing lines where space is constrained. Application-wise, it suits tool stations and actuator banks that rely on stable 0.7–17 bar outlet pressure from a G3/8 supply, improving cycle consistency. Feature → Business Impact → Application: A flexible modular system supports scalable configurations and quick accessory upgrades. Engineers can add Excelon Plus Quikclamp mounting kits or Gauge Adaptor Kits (Rc 1/8) without redesign, reducing downtime during expansions and maintenance. Application: multi-point pressure regulation along a production line. Feature → Business Impact → Application: T-bar adjustment delivers precise outlet pressure with clear, repeatable setpoints; 20 bar max inlet rating ensures compatibility with standard compressed air systems, helping to minimize regulator drift and energy waste. Application: actuator control and pneumatic tooling. Feature → Business Impact → Application: Relieving regulation streamlines venting during pressure drops, improving response times for dynamic loads. Application: high-velocity pneumatic cycles. Feature → Business Impact → Application: Durable materials—diecast aluminium body, aluminium bonnet, zinc-plated steel knob, and nitrile elastomers—support long service life in standard plant air and resist common oil-free environments. Application: general-purpose pneumatic regulation in automation cells. Feature → Business Impact → Application: Compatibility with mounting accessories like Excelon Plus General Mounting Bracket, Neck Mounting Bracket, and Quikclamp kits reduces installation complexity and allows rapid configuration changes as lines evolve.

FAQs

Begin by confirming port sizes: G3/8 for the main inlet/outlet and Rc1/8 for the gauge port if required. Use the Excelon Plus Quikclamp mounting kits for quick panel integration and ensure the unit is oriented to allow easy access to the T-bar adjustment. Tighten connections to the manufacturer’s recommended torques and verify the outlet pressure with an inline gauge after installation. This configuration minimizes vibration, reduces setup time, and keeps maintenance simple for future upgrades.
The R84G-3GT-RSN provides an adjustable outlet pressure from 0.7 to 17 bar (10 to 247 psi). This broad range supports precise control for actuators, valves, and pneumatic tools while remaining compatible with most shop air systems. For best performance, calibrate against a reference gauge after initial installation and re-check when operating conditions change.
This model is a relieving regulator, which permits controlled venting back to atmosphere to prevent overpressure in down-stream circuits. It supports a maximum inlet pressure of 20 bar, making it suitable for many standard industrial air supply systems. When configuring for relief scenarios, place the regulator to vent away from personnel and ensure exhaust lines are properly routed.
Key accessories include the Excelon Plus Gauge Adaptor Kit Rc 1/8 (840100-02KIT) for accurate in-situ pressure monitoring, the Excelon Plus Quikclamp (840014-51KIT) and with Bracket Assembly (840014-52KIT) for rapid panel mounting, and the Excelon Plus Neck Mounting Bracket and Panel Nut (840068-51KIT) for flexible installation. A general mounting bracket (840024-50KIT) completes typical setups, while the Elastomer Service Kit FRLB84-KIT supports maintenance.
Regular maintenance includes inspecting elastomer seals for wear, replacing them with the FRLB84-KIT elastomer service kit when needed, and verifying outlet pressure setpoints against a calibrated gauge. Periodic cleaning of the gauge port and checking for air leaks around fittings helps maintain accuracy. In higher usage environments, plan a quarterly reassessment of pressure regulation, especially after system changes or component replacements.
