FAQs
The R72G-3GK-NCN is designed for both inline and modular installation, using the G3/8 port and the optional Excelon accessories. Begin by confirming system air quality and mounting location, then connect the G3/8 supply and Rc1/8 gauge port if you need pressure monitoring. The modular option supports quick relocation and scalable panel layouts, reducing commissioning time and allowing future expansions without rework.
Key specs include a maximum inlet pressure of 20 bar, an outlet adjustment range of 0.3 to 2 bar (4 to 29 psi), non-relieving operation, and a flow rate of 33 dm3/sec (70 scfm). The device handles compressed air and operates between -34 and 65 °C (-29 to 149 °F). These values ensure predictable regulator behavior under typical factory conditions.
Yes, the R72G-3GK-NCN is tailored for general purpose automation requiring stable pressure in pneumatic actuators, cylinders, and grippers. Its balanced valve design and inline/modular versatility make it a strong fit for packaging lines, pick-and-place cells, and conveyor controls where consistent performance and easy installation are valued.
For regulatory compliance, verify CE marking for EU markets, IP protection ratings for environmental exposure, and SIL safety considerations when integrating with safety-related systems. While these are common benchmarks in pneumatic components, always confirm with the supplier or manufacturer documentation for your specific lot and installation.
Excelon regulators feature a push-to-lock knob and tamper-resistant options to maintain set pressure, reducing drift due to inadvertent adjustments. The in-line or modular installation simplifies retrofits, while durable zinc diecast bodies and compatible elastomer materials resist wear. Together, these factors help lower downtime and maintenance costs in a busy production environment.
