Norgren RM1H-NND-NDV Mini Regulator - Cartridge Style
Part Number: RM1H-NND-NDV
Quick Summary
RM1H-NND-NDV is a high-flow miniature precision regulator for compressed air and gas systems. Engineers frequently struggle with unstable flow, unwanted pressure drop, and limited space when integrating regulators into compact manifolds. In medical and industrial settings, CE compliance, reliable IP-rated protection, and SIL-aligned safety practices are important for risk management. The RM1H-NND-NDV features a cartridge design for easy manifold mounting, an adjustable outlet range of 0 to 2.75 bar, and a maximum inlet of 10 bar. Built for oxygen service in medical applications and for high-flow needs in automation, it delivers excellent flow, low hysteresis, and predictable performance, reducing misregulation and downtime.

Feature: Cartridge-style, high-flow regulator enables substantial gas delivery in a compact footprint, maximizing available space in crowded panels. Business Impact: This design minimizes manifold size, reduces leak paths, and lowers installed cost while preserving precise regulation and fast response times. Application: Ideal for space-constrained medical gas lines, laboratory manifolds, and compact automation panels where board space is at a premium. Feature: Adjustable outlet pressure from 0 to 2.75 bar with a 10 bar maximum inlet, giving engineers flexible regulation options across multiple lines. Business Impact: Precise, repeatable settings cut waste, improve yield, and reduce downtime caused by drift in pressure-critical processes. Application: Lab benches, pneumatic tooling, and modular automation platforms where tight pressure control is essential. Feature: Non-relieving operation ensures no unintended gas release during regulation, enhancing operator safety and system containment. Business Impact: Eliminates residual pressure spikes and improves regulatory compliance in safety-critical circuits. Application: Critical process lines, medical gas delivery paths, and safety-sensitive machinery where predictable behavior matters. Feature: PPS body and bonnet with FPM elastomers provide chemical resistance, temperature tolerance, and long-term stability in challenging environments. Business Impact: Extends service life in oxygen service and harsh industrial environments, reducing maintenance frequency and spare-part inventory. Application: Oxygen service medical devices, gas-handling modules, and rugged pneumatic equipment operating near contaminants. Feature: Flow rating of 8.3 dm3/s (17.6 scfm) supports multiple actuators and valves without bottleneck, enabling smoother cycles. Business Impact: Improves cycle times, reduces system pressure drop, and helps achieve higher overall equipment effectiveness in automation lines. Application: Pneumatic circuits in packaging, robotics, and valve banks where steady flow improves performance. Feature: Operating temperature range -5 to 95 °C expands deployment from cold labs to hot plant floors. Business Impact: Reduces design complexity by eliminating part substitutions for varying climates, lowering total ownership costs. Application: Medical labs, automotive test rigs, and field installations where ambient conditions vary.

FAQs
The RM1H-NND-NDV uses a cartridge-style design compatible with Norgren manifold configurations and cartridge ports. With a 10 bar maximum inlet and 0–2.75 bar adjustable outlet, it eases retrofit projects by reducing the need for bespoke adaptors. Properly oriented inlet/outlet connections and standard fittings ensure quick, secure installation in compact panels without compromising performance.
Key specs include a maximum inlet pressure of 10 bar, adjustable outlet pressure from 0 to 2.75 bar, non-relieving operation, and a flow capacity of 8.3 dm3/s (17.6 scfm). The regulator is designed for mediums of compressed air and gases, with PPS body and bonnet and FPM elastomers, enabling operation across a wide temperature range (-5 to 95 °C).
Yes, the regulator is described as suitable for oxygen service in medical applications. The PPS body and bonnet combined with FPM elastomers provide chemical compatibility and stability in oxygen-rich environments. When implementing in medical devices, verify material compatibility with all process gases and ensure clean, compliant installation practices.
Typical regulatory considerations include CE marking for European markets, appropriate IP protection for environmental exposure, and SIL-related safety integration for safety-critical systems. While these are common benchmarks, always confirm current certifications with the supplier or manufacturer documentation to ensure alignment with your specific regulatory and customer requirements.
The cartridge-style design simplifies manifold maintenance and replacement, reducing downtime and spare-parts inventory. Its high-flow performance, stable regulation, and non-relieving operation minimize process interruptions and waste. Over the equipment lifecycle, this translates to lower total cost of ownership and faster payback in high-throughput automation and medical gas applications.
