Norgren M/20154/40 Inline Valve - 5/2 Pilot
Part Number: M/20154/40
Quick Summary
Norgren M/20154/40 Inline Valve is a pilot-operated 5/2 valve designed for compressed air systems in automated manufacturing lines. It delivers precise, reliable control in compact spaces while keeping pipework neat through inline ports. Engineers often struggle with bulky manifolds, unstable spool seals, and difficult on-site maintenance; this valve addresses those pain points with steel reinforced spool seals and a robust aluminium body. While the data sheet notes operating range and materials, verify region-specific certifications such as CE, SIL, or IP where required. For project workflows, this valve also offers Pneufit C fitting compatibility and standard tubing, delivering quicker installation, reduced leakage paths, and lower lifecycle costs.

Feature → Business Impact → Application: Pilot-operated 5/2 valve delivers precise pneumatic control in compact automation lines, reducing footprint while improving cycle accuracy; ideal for small- to mid-sized automation cells. Feature → Steel reinforced spool seals improve stability and reliability under high-cycle duty, extending service life and reducing maintenance interruptions in production environments; suitable for high-demand timelines on assembly lines. Feature → Aluminium body reduces weight and improves heat dispersion, enabling easier installation and handling on overhead or space-constrained panels. Feature → Manual override fitted as standard enables immediate local control during setup, test, or fault conditions, cutting downtime during line start-ups or resets. Feature → Inline ports keep pipework neat and minimize leak paths, simplifying retrofits and future expansions across existing Martonair/Norgren ecosystems. Feature → Compatibility with Pneufit C push-in fittings and 12 mm tubing supports rapid installation and consistent leak performance across maintenance schedules; reduces commissioning time. Feature → Operating range 2–10 bar and temperature window 5–50 °C ensures broad applicability across standard factory air systems, with maintainable performance in typical shop conditions.

FAQs
To install correctly, ensure alignment of inline ports with existing piping and use compatible 12 mm Pneufit C fittings. Mount the valve in a clean, dry environment and provide adequate space for service access. Verify that tubing length and routing minimize bending stress, and keep the manual override accessible for quick testing during commissioning.
The valve is rated for an operating pressure range of 2 to 10 bar and an operating temperature range of 5 to 50 °C. Use within these limits ensures reliable actuation and seal integrity. For environments outside these specs, consider temperature control or alternative models with extended ratings.
Yes. The M/20154/40 is designed to integrate with the Martonair lineage and common Norgren accessories. Its inline port design and Pneufit C compatibility support straightforward retrofits, reducing piping changes and downtime. Always cross-check port sizes and thread standards (G1/2 or 12 mm fittings) against your current layout.
Yes, a manual override is fitted as standard. This feature provides immediate local control for setup, troubleshooting, and emergency testing, minimizing downtime and enabling faster fault isolation on crowded production lines. It also aids calibration and commissioning when automated control is temporarily unavailable.
The valve’s steel reinforced spool seals and aluminium body deliver durable performance with reduced wear in high-cycle applications, lowering substitution and maintenance costs. Inline ports simplify installation and future expansions, while the manual override shortens downtime during maintenance. Overall, expect lower lifecycle costs through longer service intervals and faster commissioning.
