FAQs
The R74G-6GT-RMN is designed for inline or modular installation using a G3/4 port and an optional Rc1/8 gauge port. Begin by isolating the line, then mount the regulator using compatible Quikmount or bracket options. Connect the inlet to the compressed air source, outlet to the downstream circuit, and the gauge port if monitoring is required. Tighten fittings to spec and verify no leaks with a controlled pressure ramp. The installation guide provides step-by-step instructions and torque values to ensure reliability.
Key specs include an adjustable outlet range of 0.3 to 10 bar, maximum inlet pressure of 20 bar, and a flow capacity of 105 dm3/sec (222 scfm). The unit is a Relieving Excelon general purpose regulator with T-bar adjustment for fast setpoint changes and inline or modular installation. These specs support precise regulation in general pneumatic circuits while accommodating higher-demand actuation without sacrificing stability.
Yes. With a 105 dm3/sec (222 scfm) flow rating and a 0.3–10 bar regulation range, the regulator maintains consistent downstream pressure even during peak demand. Its balancing valve design minimizes drift, and the Relieving feature protects downstream equipment when lines are dead-ended. For Retrofit or new builds, use the Excelon accessories like porting blocks and mounting brackets to ensure optimal integration.
Certifications for this product are aligned with standard industrial practice; exact coverage (for CE, IP ratings, SIL, etc.) should be confirmed in the datasheet. The provided datasheets and installation guide contain the official certification statements and compliance notes. Always verify current certification status against your regional requirements before deployment in regulated environments.
Maintenance is simplified by the T-bar adjustment and robust Excelon construction, reducing the need for frequent recalibration. The regulator’s stable pressure support lowers process variability and defect rates, delivering operational efficiency and potential cost savings over time. Durable aluminium body and nitrile elastomer seals withstand typical industrial environments, reducing replacement intervals and downtime.
