IMI Norgren M/21/70 Inline Valves - Manual/Mechanical 3/2

Light, compact body reduces panel footprint and enables easier retrofits in crowded control enclosures. This supports valve islands and multi-valve manifolds where space is at a premium, while maintaining reliable airflow control. The result is faster installation, improved cabinet organization, and predictable maintenance schedules for system integrators. Very low pilot pressure minimizes energy use in pilot circuits, lowering overall system power consumption and reducing wear on upstream components. This translates to lower operating costs and longer service life in high-cycle applications, such as packaging lines and pressurized assembly cells. The air bleed principle provides fast, controlled venting, improving response times and tightening cycle accuracy. An exhaust port protected by a filter disc reduces dust intrusion and contamination, boosting longevity in dirty factory environments and minimizing maintenance interruptions. These design choices support higher line uptime and lower total cost of ownership in automated pneumatic systems. Low operating force makes manual actuation effortless in tight panels or awkward mounting locations, enhancing operator comfort and reducing the risk of fatigue during long production runs. This improves control precision and consistency, especially in high-mix, low-volume production scenarios where setup changes are frequent. Materials selection—body in zinc alloy, piston in steel, seals in nitrile rubber—provides durable service in standard industrial environments, resisting wear and chemical exposure while maintaining tight leak integrity. The combination supports robust performance across the 5–80 °C temperature range and 4–10 bar operating pressure, aligning with typical factory air supply conditions. Range M/21 and the Martonair series compatibility ensure seamless integration with existing IMI Norgren components, from fittings to tubing and actuation accessories. Push-in fittings (Pneufit C) and 6 mm tubing compatibility streamline installation, reduce leak paths, and cut assembly time in new builds or retrofits. Overall, these features enable faster commissioning, lower maintenance overhead, and reliable repeatability in demanding automation environments.
