Norgren M/20134/122/MDZ83J Inline Valves - Solenoid 3/2
Part Number: M/20134/122/MDZ83J
Quick Summary
Inline Valves are a solenoid-driven control solution for precise compressed air actuation in automated manufacturing. They address common pain points like leaks, sluggish response, and space constraints on crowded pneumatic manifolds. In practice, look for CE compliance and IP ratings where applicable, and verify SIL compatibility in safety-critical lines. The M/20134/122/MDZ83J version strengthens reliability, while aluminium body and nitrile seals support durable, maintenance-friendly operation. These features support efficient, low-maintenance pneumatic systems in industrial automation, reducing downtime and total cost of ownership. For engineers, this translates to quicker line changes, easier diagnostics, and clearer documentation across service intervals. That combination helps meet demanding production schedules and reduces risk of unplanned downtime.

Inline valve construction with in-line ports keeps pipework neat and tidy, enabling faster installation and easier future reconfigurations while steel reinforced spool seals enhance stability and reliability in vibration-prone environments. Business impact: reduced assembly time, lower leak potential, and improved cycle consistency across packaging and automation lines. Application: ideal for compact skids and panels where space is at a premium and clean routing is required. The aluminium body reduces weight without sacrificing rigidity, supporting quicker retrofit and safer handling during maintenance. Seals made from nitrile rubber provide chemical resistance to common lubrication and lubricants used in pneumatic systems, extending service intervals and lowering lifecycle costs. Operational range of 5 to 50 °C and 2.5 to 10 bar enables reliable performance across typical factory environments. These features work seamlessly with 12 mm Pneufit C fittings, 90° elbows, and standard straight adapters, simplifying installation and replacement. The 3/2 valve operation supports straightforward actuating logic for standard single-acting cylinders. This Martonair valve line from IMI Norgren is known for durability and predictable response, which translates into higher line throughput and safer automation. In practice, users appreciate the built-in manual override for diagnostic testing and maintenance checks, reducing downtime during fault isolation. As a field-tested solution, it integrates with C02471248 and C02251248 push-in fittings and T40C4800 silencers to minimize noise in intensive production environments. For upgrades, the modularity of the Tubing PA2-0012025C and PA2-0012100 lines simplifies expansion, inventory management, and spares availability. Overall, the MZ83J variant brings a balanced blend of performance, installation ease, and long-term cost efficiency.

FAQs
Installation involves connecting the 12 mm Pneufit C push-in fittings to the inline ports, using the 90° swivel elbow or straight adapters as required to maintain neat piping. The valve body is aluminium for light weight, and the kit typically includes or is compatible with PA2-0012025C tubing. Ensure the operating pressure is within 2.5-10 bar and the temperature is within 5-50 °C for reliable performance. A built-in manual override simplifies diagnostics without removing electrical power, reducing commissioning time and enabling quick functional checks on site.
Core pneumatic specs include compressed air as the medium, operating pressure 2.5-10 bar, and operating temperature 5-50 °C. The valve operation is 3/2, and the body is aluminium with nitrile seals. For electrical compatibility, verify the exact coil voltage and connector type with your supplier, as these details vary by installation and control system. Ensure the signal and power supply meet your safety requirements and consider incorporating standard safeguards around solenoid actuation to support SIL-capable safety configurations.
The provided data does not specify SIL certification for this exact model. For safety-critical applications, confirm with Norgren documentation or your supplier whether a SIL-rated variant is available or if this valve can be integrated into a SIL system with appropriate interlocks and safety circuits. In practice, plan for proper risk assessment, use of certified safety relays or controllers, and independent verification of the complete control loop to meet industry safety standards.
The aluminium body reduces weight without compromising rigidity, aiding quicker replacements and safer field servicing. Steel reinforced spool seals improve reliability in dynamic cycles, lowering leak rates and reducing energy waste. The integrated manual override and compatibility with common fittings streamline maintenance checks and spare-part management, enabling faster troubleshooting and shorter downtime. Over the lifecycle, these factors translate to improved uptime, predictable performance, and a lower total cost of ownership, especially on high-volume automation lines.
Recommended accessories include Pneufit C push-in fittings (C02471248 and C02251248), silencers such as T40C4800 for noise reduction, and polyamide tubing PA2-0012025C or PA2-0012100 for flexible, durable pneumatic runs. A tube cutter (M/3314) is handy for clean, on-site tube preparation. These components align with the valve’s porting, 12 mm tubing, and G1/2 connections, ensuring a clean, reliable, and scalable pneumatic assembly.
