Norgren SCSQ101D01D02400 3/2 Safety Valve - IP65
Part Number: SCSQ101D01D02400
Quick Summary
Norgren SCSQ101D01D02400 3/2 Safety Valve provides reliable, self-monitoring control of compressed air in safety-critical machinery. Engineers often struggle with extra safety circuits and cyclic monitoring, which add setup time and integration risk. With IP65 ingress protection, DGUV approval, and DIN EN ISO 13849-1 performance level e (Cat. 4) when applied correctly, it meets demanding safety standards. The integrated soft-start function and direct-mount compatibility to Excelon 73/74 air preparation products simplify installation, reduce wiring, and lower total cost of ownership in industrial automation environments. This makes it particularly attractive for mid- to high-volume lines where uptime and safety compliance drive procurement decisions.

Redundant valve assembly with pneumatic self-monitoring and an integrated silencer delivers safer operation with quieter lines. The self-monitoring design eliminates the need for separate cyclical testing or external evaluation systems, reducing wiring, panels, and maintenance tasks while maintaining fail-safe integrity on safety functions. Integrated soft-start function reduces pressure ramps at valve actuation, minimizing shock loads on fittings and downstream equipment. This translates into longer seal life, fewer leaks, and reduced energy consumption during start-up sequences. Direct-mount compatibility to Excelon 73/74 air preparation products simplifies installation and reduces piping, leak paths, and assembly time. The G1/2 port size and 3/2 NC operation make it straightforward to replace legacy units in compact control panels. Aluminium body and polyurethane seals deliver robust performance in industrial environments, while IP65 protection withstands wash-down and dust ingress. DGUV approval and DIN EN ISO 13849-1 PL e (Cat. 4) support regulatory compliance for safety functions. With a flow of 2450 l/min and rated operating pressure of 2.5–10 bar, this valve supports high-demand applications in manufacturing and packaging lines. The 3/2 valve operation and NC configuration suit fail-safe logic, and the modular construction supports straightforward replacement and spare-part availability. Direct fit in medium-pressure pneumatic circuits, weight 1.1 kg, body aluminum, and 12 mm tubing options facilitate ease of procurement, inventory management, and serviceability; it's a reliable choice for engineers aiming to minimize downtime.

FAQs
Yes. The SCSQ101D01D02400 is designed for direct mounting to Excelon 73/74 air preparation products, reducing piping and installation time. With G1/2 ports and a compact aluminium body, it can replace legacy 3/2 valves in control panels without extensive adapters. For best results, use Pneufit C fittings and follow Norgren installation instructions.
Certifications include IP65 ingress protection, DGUV approval, and DIN EN ISO 13849-1 performance level e (Cat. 4) for the safety function when applied correctly. These standards support safe operation in harsh industrial environments, meet regulatory expectations, and simplify risk assessment during audits or customer approvals. The integration-friendly design reduces validation time and supports compliance documentation.
Key specifications influencing performance on high-speed lines include operating pressure 2.5–10 bar, flow 2450 l/m, G1/2 port size, and 3/2 NC operation with solenoid pilot/spring return. The device is rated for -10 to 60 °C and compressed-air media, with an integrated soft-start that minimizes pressure spikes and mechanical stress on downstream equipment.
Yes. The IP65 rating and polyurethane seals provide robust protection against dust and wash-down exposure, making the valve suitable for many manufacturing, packaging, automotive, and general automation environments. For best results, pair with appropriate manifolds and follow standard installation practices to maintain ingress protection and system integrity.
Adopting this valve can shorten project timelines and reduce life-cycle costs. By simplifying safety circuitry and enabling direct mounting, it lowers installation hours and spare-part inventories. The DGUV-approved, ISO 13849-1 PL e safety function helps with audits and compliance, improving overall equipment effectiveness (OEE) and return on investment in automation projects.
