FAQs
The R82G-2AK-RFG uses a 1/4 inch PTF port for the main inlet, plus a 1/8 inch PTF gauge port for status monitoring. Its compact die-cast aluminum body supports panel mounting in space-constrained environments, with a flush gauge that simplifies inline diagnostics during start-up and routine maintenance.
Outlet pressure is adjustable from 0.3 to 4 bar (4 to 58 psi), with a maximum inlet pressure of 20 bar. It is a relieving regulator, meaning it actively vents pressure when the set point is exceeded, helping protect downstream components and maintain safe system depressurization in fault conditions.
Yes, it is part of the Excelon Plus family designed for modular, reliable compressed air regulation. For maintenance, relies on standard inspection of the gauge port, knobs, and seals; use approved replacement elastomers as needed; ensure proper re-calibration after any field adjustments to maintain accuracy and repeatability.
Install with adequate clearance for airflow and gauge visibility, and orient the unit to align the gauge port for easy readings. Use the panel’s minimum footprint efficiently by leveraging the regulator’s compact dimensions, and protect against contamination in harsh environments with appropriate enclosure protection where available.
Expect reduced downtime due to rapid diagnostics via the integrated gauge, lower misadjustment risk from the tamper-resistant knob, and longer tool life from stable pressure regulation. The compact form supports smaller panels and fewer components, contributing to lower install and maintenance costs over the regulator’s lifecycle.
