Norgren RM1L-1GD-NCV Precision Regulator - Non-relieving
Part Number: RM1L-1GD-NCV
Quick Summary
RM1L-1GD-NCV precision regulator is a compact device that delivers stable downstream pressure for compressed air in medical and automation applications. Engineers often struggle with pressure fluctuations and wasted energy in tight spaces, which this regulator helps mitigate with precise adjustment and low hysteresis. The design targets oxygen service and medical applications, while also performing reliably with general compressed air. Note that certification details such as CE, SIL or IP ratings are not listed in this datasheet; confirm regulatory compliance with Norgren for your region. By combining robust materials with accurate control, this regulator supports uptime, reduces waste, and enables consistent performance in demanding environments.

Feature: G1/8 port size enables a compact, easy-to-integrate footprint for small manifolds and panel installations. Business impact: simplifies installation, reduces space requirements, and lowers assembly complexity. Application: ideal for compact automation booths and instrument panels where space is at a premium. Feature: Maximum inlet pressure of 10 bar provides a safe, standard-compliant supply range from typical plant air lines. Business impact: minimizes need for oversized regulators and improves system reliability. Application: automotive, packaging, and automation lines with standard plant air feeds. Feature: Outlet pressure adjustment range of 0 to 2 bar (0 to 30 psi) enables precise regulation for sensitive loads. Business impact: tighter control improves process stability and reduces variance. Application: calibrated instruments, pneumatic grippers, and process controls that demand low, steady setpoints. Feature: Non-relieving design prevents downstream bleed and maintains pressure in closed-loop systems. Business impact: enhances stability, reduces leak-induced drift, and supports energy efficiency. Application: closed-loop regulators in medical and industrial settings where inadvertent venting is undesirable. Feature: Flow rating of 3.3 dm3/sec (7 scfm) meets modest flow demands without oversized hardware. Business impact: lowers capital cost and total system pressure drop while preserving response speed. Application: micro-scale regulators, pilot lines, and small automation circuits. Feature: Aluminium body, PPS bonnet, and FPM elastomers deliver robust performance with suitable chemical and temperature tolerance. Business impact: longer service life in demanding environments, including oxygen-service contexts. Application: harsh manufacturing environments and healthcare-oriented gas applications. Feature: Designed for oxygen service and medical applications, with excellent flow and predictable pressure behavior. Business impact: supports regulatory-minded installations while enabling reliable, repeatable performance. Application: medical devices, hospital supply lines, and precision automation where gas regulation is critical.

FAQs
The RM1L-1GD-NCV uses a G1/8 port. For installation, mount the regulator in a stable orientation using compatible fittings, connect the inlet supply, and secure with appropriate brackets. Use the adjusting screw to set the desired outlet pressure within 0–2 bar. Ensure the line is clean and free of contaminants before final commissioning.
The regulator provides an outlet pressure range of 0 to 2 bar (0 to 30 psi) and a maximum inlet pressure of 10 bar. It is a non-relieving device, so it does not vent pressure to atmosphere when adjusted. Typical flow is 3.3 dm3/sec, suitable for modest demand applications.
Yes. The RM1L-1GD-NCV is described as suitable for oxygen service and medical applications, featuring materials and elastomers chosen for compatible exposure to medical gases. Always verify regional regulatory requirements and perform compatibility testing for your specific medical system or device.
The provided data does not list specific certifications such as CE, SIL, or IP ratings. For regulatory compliance in your region, consult Norgren directly and request certified documentation. In practice, medical and hospital-grade implementations typically require supplier validation and third-party conformity tests aligned with local regulations.
Schedule periodic inspection for leaks and wear, verify the outlet setpoint remains stable, and clean the ports to prevent contamination. Replace elastomers as needed and document regulator performance to track uptime. A stable, well-maintained regulator reduces process variability, extends component life, and lowers energy and maintenance costs over time.
