Norgren SCVA081BB0A02400 3/2 Safety Valve - IP65
Part Number: SCVA081BB0A02400
Quick Summary
SCVA081BB0A02400 is a 3/2 self-monitoring safety valve designed for compressed-air circuits. It eliminates the need for cyclical external monitoring and reduces the risk of unintended pressure events in loading and venting applications. The device supports safety performance up to SIL e (Category 4) per DIN EN ISO 13849-1 with DGUV approval and carries IP65 ingress protection for demanding environments. Built from aluminium with polyurethane seals, it delivers durable, leak-tight operation in factory floors. By combining compact form with robust safety features, it helps engineers meet regulatory requirements while achieving reliable cycle times and lower total cost of ownership.

Redundant valve assembly with pneumatic self-monitoring and integrated safety silencer enhances overall plant safety by removing the need for cyclical monitoring and reducing nuisance trips, enabling faster cycle times in high-risk lines. The 3/2 NC valve with G1/4 ports provides predictable actuation and straightforward integration with existing pneumatic manifolds, supporting common automation architectures. An aluminium body with polyurethane seals delivers robust durability and reduced leakage in harsh environments, while IP65 protection keeps performance stable in dusty or damp factory floors. The 1280 l/min flow rate enables responsive loading/venting cycles, improving throughput and reducing cycle times. Compliance features, including SIL e (Cat 4) per ISO 13849-1 and DGUV approval, simplify regulatory compliance for safety-critical applications. The solenoid pilot with spring return offers reliable fail-safe operation and easy electrical integration, minimizing wiring complexity and installation costs.

FAQs
Install with standard G1/4 threaded ports on a compatible manifold. Ensure supply pressure is within 3–10 bar and provide a suitable voltage for the solenoid pilot. Use correct mounting orientation for best silencing performance and verify IP65-rated enclosure integrity in dusty or damp environments. The unit’s self-monitoring design reduces the need for external feedback loops, simplifying wiring and commissioning.
The SCVA081BB0A02400 delivers a rated flow of 1280 l/min (45.2 scfm) at its operating pressure range of 3–10 bar. It is a 3/2 NC valve with solenoid pilot and spring return, enabling reliable and repeatable actuation. Actual cycle times depend on system pressure, supply stability, and load characteristics, but the integrated silencer helps maintain acceptable noise levels during rapid cycling.
The valve supports safety functionality up to SIL e (Category 4) per DIN EN ISO 13849-1 and carries DGUV approval, along with IP65 ingress protection. This combination helps you meet machine safety requirements and regulatory expectations without additional external monitoring, particularly in safety-critical loading and venting circuits.
The valve operates from -10 to 60 °C and is rated for compressed air at 3–10 bar. Its aluminium body with polyurethane seals provides durability in industrial settings, and the IP65 rating ensures protection against dust and water ingress. This makes it suitable for factory floors, automation panels, and other challenging environments.
With integrated self-monitoring and no requirement for cyclical external evaluation, maintenance can be reduced and system downtime minimized. The compact, durable design lowers replacement frequency, while the silencer reduces noise-related compliance concerns. Regulatory certifications and robust construction contribute to predictable performance, potentially lowering lifecycle costs and improving overall return on investment.
