FAQs
The R84G-3GK-RMN uses standard G3/8 plumbing and Rc1/8 gauge port fittings. For quick mounting on existing lines, use Excelon Plus mounting options such as 840024-50KIT (General Mounting Bracket) and 840068-51KIT (Neck Mounting Bracket and Panel Nut). For gauge monitoring, attach 840100-02KIT Gauge Adaptor Kit. The push-to-lock knob provides tamper resistance, helping to maintain setpoints in busy environments.
The regulator provides a 0.3 to 10 bar outlet range (4 to 145 psi) with a max inlet of 20 bar. Set pressure using the knob; the push-to-lock feature secures the setting after adjustment. Relieving operation venting helps maintain safe venting when pressure changes occur, which is particularly important on packaging lines and automated cells.
Yes. It is designed for compressed air regulation in automation and packaging applications, featuring a compact diecast aluminium body, a 0.3–10 bar range, relieving functionality, and compatible with Excelon Plus accessories such as gauge adapters and mounting brackets. With a flow capacity of 125 dm3/sec (265 scfm), it supports demanding line demands while maintaining stable pressure.
Refer to the datasheet and product documentation for certification details such as CE/UKCA marking status and IP ratings. The R84G-3GK-RMN is part of the Excelon Plus family and is designed for standard industrial use in pneumatic systems; confirm regulatory compliance for your region and application via the official datasheet.
Maintenance options include elastomer service kits FRLB84-KIT for the R84G family and the Excelon Plus gauge adaptor kit 840100-02KIT. Regularly inspecting elastomer seals and replacing with the FRLB84-KIT helps preserve performance in harsh environments, while gauge adapters simplify pressure monitoring for ongoing performance audits.
