The RM1H-1GD-NCV delivers high-flow, miniature precision regulation for demanding automation lines. With a rated flow of 8.3 dm3/sec (17.6 scfm) and a compact G1/8 port, it ensures fast actuator response and tight pressure control even when multiple valves cycle simultaneously. Engineers appreciate the combination of compact footprint and high capacity, which enables denser layouts and fewer components in the pneumatic network. Durability and chemical compatibility are built in. The aluminium body stands up to industrial environments, while the PPS bonnet provides heat resistance and structural integrity at elevated temperatures. Elastomer seals made from FPM withstand petroleum and oxygen-enriched applications, reducing risk of degradation in routine maintenance cycles. The non-relieving design minimizes venting under fault or shutdown, improving safety and minimizing noise in cleanroom or production-area installations. Adjustment precision and safety features translate into measurable process improvements. Outlet pressure is adjustable from 0 to 2 bar (0 to 30 psi), with a maximum inlet pressure of 10 bar, delivering stable downstream performance across a range of tools and actuators. The adjusting screw offers repeatable setpoints, while the non-relieving topology reduces backflow or unintended venting. This combination supports tighter control loops and lower energy consumption, enabling cost reductions in compressed air systems. Operating range supports diverse environments. Temperature tolerance of -5 to 95 °C ensures operation from chilly factory bays to warm equipment rooms, while compatibility with compressed air and gases expands its utility beyond standard pneumatic circuits. Lightweight construction and common port size simplify installation and retrofits, and the unit can integrate with existing Norgren or third-party fittings, reducing installation time and potential leakage points. Practical installation and maintenance benefits. The RM1H-1GD-NCV's G1/8 port, robust materials, and straightforward adjustment pattern mean fewer service calls and predictable performance over time. In medical and industrial contexts where precise pressure and clean operation matter, this regulator supports compliance with general industry standards and helps ensure stable automation performance, uptime, and ROI on fluid control investments.

FAQs
For reliable installation, ensure compatible G1/8 fittings and seals are used, verify alignment with downstream components, and consider momentary pressure surges in your feed line. The non-relieving design helps minimize venting in fault conditions, while the aluminum body and PPS bonnet simplify mounting in confined spaces. Use appropriate sealants and torque guidelines to prevent leaks without over-tightening the port connections.
The regulator is specified as suitable for oxygen service, which supports operations in medical and health-related environments. In practice, it delivers stable outlet pressure with low hysteresis and a robust structural design that tolerates the demands of regulated gas flows. Confirm regional regulatory approvals with your supplier to ensure full compliance for your specific medical installation.
Key specs include a maximum inlet pressure of 10 bar and an adjustable outlet range from 0 to 2 bar (0–30 psi). The unit provides a high flow rate of 8.3 dm3/s (17.6 scfm), supporting rapid response in actuated pneumatic circuits. Plan for peak demands by incorporating proper valve sizing and piping to maintain stable downstream pressure.
Certification details such as CE, IP ratings, or SIL conformity are not listed in the provided data. To validate compliance for your application, consult the supplier or distributor for the exact certifications and any conformity declarations relevant to your region and industry. This ensures alignment with regulatory requirements and internal quality standards.
The regulator’s non-relieving design, durable aluminium body, PPS bonnet, and FPM elastomer seals contribute to reduced leakage and longer service intervals. High-flow capability supports efficient pneumatic loops, potentially lowering energy consumption. Over time, fewer regulator replacements and less downtime translate into improved uptime, predictable process performance, and a favorable return on investment for automation projects.
