Norgren RM1L-NND-NFV Valves & Flow Control - Cartridge Reg
Part Number: RM1L-NND-NFV
Quick Summary
RM1L-NND-NFV is a low-flow miniature precision regulator for compact pneumatic systems in medical and industrial settings. Small footprint and tight flow control often complicate oxygen service and manifold integration. Certification options such as CE, SIL, and IP ratings are commonly specified by end users and system integrators to meet regulatory and safety requirements. This cartridge-style regulator uses PPS body and FPM elastomers to deliver reliable performance across -5 to 95 C and up to 10 bar inlet pressure, with stable 0–4 bar outlet settings. Coupled with Norgren's broader ecosystem, RM1L-NND-NFV offers predictable operation, fast installation, and reduced total cost of ownership across OEM lines.

FAQs
Begin with confirming cartridge port alignment and torques specified by Norgren. Remove the regulator housing, insert the cartridge into the manifold slot, and tighten with the adjusting screw accessible from the bonnet. Ensure the inlet is clean and the medium matches the rated compressed air or gas. After installation, verify that the outlet pressure range is set to 0–4 bar using calibrated gauges and test for leaks in the system.
The regulator supports a maximum inlet pressure of 10 bar and provides an adjustable outlet range of 0–4 bar (0–60 psi). It is a non-relieving regulator with a flow capacity of 3.3 dm3/sec (7 scfm). The operating temperature range is -5 to 95 °C (23 to 203 °F). The body and bonnet are made of PPS with FPM elastomers, optimized for reliability in pneumatic and light-gas applications.
Yes, RM1L-NND-NFV is described as suitable for oxygen service and medical applications. Its PPS body with FPM elastomers and cartridge design support cleanliness and compatibility in regulated environments. When deploying in medical devices, verify system-level certifications and perform a commissioning protocol to confirm compatibility with your specific oxygen purity requirements and regulatory expectations.
Certification requirements are typically defined by the end user and system integrator. While the product data highlights general suitability for medical and industrial use, you should confirm CE, SIL, IP and other certifications with your supplier or system team based on your geographic and regulatory needs. Always document compliance mapping to your device’s risk assessment and quality management system.
The cartridge design simplifies field servicing and replacement, reducing downtime. PPS body and FPM elastomers offer chemical resistance and long-term stability, limiting downtime due to wear. Its non-relieving build provides predictable pressure behavior, which reduces recalibration frequency. In multi-valve manifolds, the modular cartridge approach lowers spare-part variety and accelerates maintenance workflows, delivering lower total cost of ownership over the system lifecycle.
