FAQs

Begin by selecting a suitable mounting bracket from the Excelon Plus family, such as the 840024-50KIT general mounting bracket, and attach the regulator to a clean, shaved panel. Connect the 1/2" PTF supply line to the inlet, use the 1/8" PTF gauge port for monitoring, and secure with the panel nut kit if required. Verify orientation, tighten fittings to spec, and test at low pressure before full operation.
The R84G-4AT-RSN provides an outlet pressure range of 0.7 to 17 bar (10 to 247 psi) with a maximum inlet pressure of 20 bar. It delivers a flow of 125 dm3/s (265 scfm), enabling rapid stabilization of downstream circuits while maintaining regulator responsiveness across typical automation loads.
Yes. Its Relieving design supports safe venting under transient overloads, while the Excelon Plus platform offers a compact, modular build suitable for high-cycle environments. The diecast aluminium body and nitrile elastomer seals provide durability, and the T-bar adjustment allows quick field calibration to maintain consistent packaging and assembly line performance.
The R84G-4AT-RSN aligns with CE-compliant design practices typical of European industry standards. For a complete list of approvals and regional certifications, consult the datasheet and installation guide available from Norgren, or contact your distributor to confirm current certifications for your region and application.
Maintenance can be streamlined with the Excelon Plus Elastomer Service Kit FRLB84-KIT and the Gauges Kit 840100-01KIT for quick calibration checks. Spare mounting components such as 840024-50KIT brackets and 840048-89KIT Panel Nut assist in rapid retrofits. Regular checks of the nitrile seals and T-bar assembly extend service life and reduce unexpected downtime in production lines.
