Norgren RM1L-NND-NAV Low-Flow Regulator - Cartridge Style
Part Number: RM1L-NND-NAV
Quick Summary
RM1L-NND-NAV is a precision cartridge-style regulator for miniature pneumatic control in medical and automation applications. Engineers often struggle to find compact regulators that deliver stable output with low pressure drop in space-constrained manifolds. In regulated environments, CE marking is a common requirement, and many systems also demand SIL-capable safety features or IP-rated enclosures to meet compliant operations. The RM1L-NND-NAV’s oxygen-service suitability and cartridge design support faster assembly, reliable performance, and reduced total cost of ownership across medical and industrial lines. This combination delivers tangible value for design engineers and procurement teams alike, while enabling scalable deployments in tightly packaged systems.

FAQs
For cartridge-style manifold integration, ensure the regulator is mounted in a location with adequate clearance for the cartridge insert and adjustment screw access. Use compatible PPS body hardware and correct elastomer seals (FPM) to maintain gas compatibility. Verify inlet pressure does not exceed 10 bar and that downstream components tolerate 0–0.35 bar outlet pressures. Proper torque on mounting fittings helps prevent leaks and ensures consistent regulation.
The unit is designed for compressed air and gases and is suitable for oxygen service in medical and related applications. Ensure all downstream components are compatible with the chosen gas medium and that system cleanliness is maintained to prevent contaminants from affecting regulation. Material choices—PPS for body and bonnet, FPM elastomers—support chemical compatibility in typical gas handling environments.
Outlet pressure is adjustable from 0 to 0.35 bar (0 to 5 psi) using the adjusting screw. The cartridge-style design minimizes hysteresis for repeatable setpoints, and the non-relieving configuration helps maintain downstream pressure under steady-state conditions. This makes the regulator well-suited for sensitive actuators and instrumentation requiring stable pressure control.
The RM1L-NND-NAV features PPS bodies and bonnet, providing chemical resistance and structural stability across typical pneumatic and gas-handling environments. FPM elastomers offer good resistance to fuels and many chemicals, improving long-term sealing performance. These material choices support oxygen service and help minimize contamination risk in medical and industrial deployments.
Its cartridge design simplifies installation and maintenance, reducing assembly time and field downtime. The combination of compact size, stable outlet pressure, and robust materials lowers the risk of leaks and regulator failures, contributing to longer service intervals and fewer warranty issues. Overall, it supports faster time-to-market and lower lifecycle costs for OEMs and maintenance teams.
