Feature → Business Impact → Application: The R84G-3GK-RFG integrates a compact die-cast aluminum body with a G3/8 port, reducing overall system size and weight while maintaining robust durability in demanding environments. This directly translates to lower installation costs, easier retrofits, and improved energy efficiency in automated lines that demand precise pressure control. Application-wise, it suits compact pneumatic manifolds, tooling devises, and robotics grippers where space is at a premium and consistent pressure is critical. Feature → Business Impact → Application: The knob-operated adjustment with built-in tamper resistance minimizes drift from unauthorised adjustments, increasing process stability and safety in critical automation cells. This is particularly valuable in high-mix production where quick line changes occur without sacrificing regulation accuracy. Feature → Business Impact → Application: The integrated gauge plus relieving design provides immediate visibility and safe pressure management, reducing downtime during commissioning and service. Industry teams benefit from faster setup, easier maintenance, and compliance-friendly installation in EU and global facilities. Feature → Business Impact → Application: Operating across -20 to 65 °C, with a maximum inlet pressure of 20 bar, supports reliability in washdown and high-temperature zones, enabling use in versatile manufacturing lines. This helps systems stay within spec during start-up, shutdown, and environmental fluctuations. Feature → Business Impact → Application: With a 0.3–4 bar adjustable output and a flow capacity of 125 dm3/sec, the regulator delivers consistent actuation force for pneumatic cylinders and valves, improving cycle times and reducing waste. This is ideal for grippers, pick-and-place modules, and automation manifolds where timing and precision matter. Feature → Business Impact → Application: The Excelon Plus design uses compatible materials (acetal knob, die-cast body, POM bonnet, nitrile elastomers) that resist wear and provide predictable performance, reducing spare-part consumption and service costs over the product lifetime. This supports total cost of ownership targets in mass production and OEM tooling programs.

FAQs

Yes. The regulator uses a G3/8 inlet/outlet port and Rc1/8 gauge port, designed for common pneumatic systems. The flush-mounted integrated gauge simplifies alignment during panel mounting and minimizes space requirements in compact installations, reducing assembly time and potential misconnection.
The unit provides a 0.3 to 4 bar adjustable outlet range with a maximum inlet pressure of 20 bar. This combination supports stable actuation across typical pneumatic cycles while enabling precise flow control for actuators, valves, and tooling components.
Ideal for automated manufacturing lines, robotics end-effectors, and compact pneumatic manifolds where space is constrained. Its relief design and integrated gauge enhance safety and quick commissioning in assembly, packaging, and pick-and-place systems requiring reliable, repeatable pressure control.
This model is part of the Excelon Plus family and is designed with European safety and quality expectations in mind. For exact certification status (CE marking, IP ratings, etc.), consult the datasheet and installation guide linked in the product downloads to confirm current approvals for your region.
Leverage the Excelon Plus elastomer service kit FRLB84-KIT for elastomer replacements to sustain seal integrity and performance. The integrated gauge and tamper-resistant knob reduce drift and downtime during maintenance, contributing to lower total cost of ownership in high-demand production environments.
