FAQs
The R72G-3GK-RMN supports both inline and modular installation, enabling flexible mounting to suit compact panels or larger automation racks. With a G3/8 port and Rc1/8 gauge port, it can be integrated alongside standard pneumatic components, making retrofits straightforward and minimizing disruption to existing line layouts.
The regulator provides 0.3 to 10 bar outlet pressure control on a 20 bar maximum inlet, with a balanced valve design to reduce drift during fluctuating loads. This combination supports stable downstream pressure across typical automation and manufacturing applications while allowing precise adjustment via the knurled knob.
Yes. With a flow capacity of about 33 dm3/s (70 scfm), the R72G-3GK-RMN accommodates typical medium-scale pneumatic circuits found in automation cells, conveyors, and pick-and-place equipment while maintaining tight pressure control and fast response to demand changes.
The unit includes a push-to-lock adjusting knob for secure setup and a tamper-resistant accessory option to prevent inadvertent setting changes. Its relieving model helps safely manage downstream pressure when the system is dead-ended, adding an important safety margin for automated processes.
