FAQs

The R84G-4GT-RSN supports a compact panel-mount approach within the Excelon Plus family and is compatible with mounting kits such as 840024-50KIT (General Mounting Bracket) and 840068-51KIT (Neck Mounting Bracket and Panel Nut), enabling flexible installation on standard control panels and compact assemblies.
Key specs include a G1/2 port size, Rc1/8 gauge port, 0.7–17 bar output range, 20 bar maximum inlet pressure, Relieving operation, and a flow of 125 dm3/sec. These figures support reliable pressure regulation across typical pneumatic circuits in automation environments.
Yes. The Relieving type configuration helps vent excess pressure safely, protecting downstream actuators and reducing the risk of overpressure in high-cycle or fluctuating load scenarios common in packaging and automation lines.
