Quick Summary

Norgren S/666/117 inline valve provides reliable pneumatic control for compact automation lines. With a compact footprint, it fits tight panels and crowded assemblies without compromising performance. When installation time is critical, a robust long-lever actuation and panel-mount option minimize setup and misalignment. In European and global operations, CE compliance is commonly required for automation equipment, IP-rated protection is expected in factory environments, and SIL safety considerations influence how valves integrate into safety circuits. This valve aligns with mainstream pneumatic systems, maintaining compatibility with Pneufit C fittings and Quietaire silencers for quieter operation, while delivering low-weight, reliable service. The result is a cost-effective solution for streamlined production and easier maintenance.

Compact, robust design enables space-saving installation in crowded control panels, reducing footprint and enabling easier routing of air lines. Feature → Business Impact → Application: The small form factor translates to faster installation and fewer panel modifications, speeding project timelines in automated packaging or assembly lines. Application: Use in tight control cabinets where space is premium and reliability is essential. Long-lever actuation and panel-mount options provide tactile, repeatable control for operators, improving cycle consistency and reducing set-up time during line changes. Application: Manual override and quick-positioning tasks on bench-top or machine-mounted panels. 3/2 valve function with normally closed operation ensures safe default states, protecting actuators and preventing unintended cylinder extension. Application: Pick-and-place modules and single-acting cylinder circuits where fail-safe behavior matters. G1/8 port size offers compatibility with standard Pneufit C fittings, minimizing leak paths and simplifying tubing layouts. Application: Retrofit on existing 1/8-inch pneumatic circuits without major modifications. Operating range -20 to 80 °C and 2 to 10 bar supports diverse industrial environments, from cooling lines to hot CNC rooms. Application: Suitable for machinery across varying ambient conditions, reducing the need for multiple valve variants. Weight of 0.2 kg and compact dimensions (75 × 34 × 19 mm) contribute to lighter moving mass and easier integration into compact automation modules. Application: Ideal for modular machines and compact automated stations where weight matters. Optional Silencer, Fittings, and Tubing from the Norgren family (Quietaire, Pneufit C adapters, PA2 tubing) enable a complete, ready-to-install solution. Application: Streamlined procurement and reduced project risk through integrated components.

FAQs

Yes. The valve uses a G1/8 port and is designed to integrate with Pneufit C push-in fittings, simplifying tubing routes and reducing the risk of leakage. This compatibility supports quick retrofits and streamlined assembly in existing systems.
The valve is a 3/2, normally closed (NC) inline valve with lever actuation, delivering reliable, repeatable control for single-acting cylinders. Its compact size and light weight help minimize inertial effects, improving response times in fast-processing applications.
Yes. With a panel-mount option and a broad operating temperature range (-20 to 80 °C) plus a 2–10 bar operating pressure range, it is well-suited for industrial environments. For harsher settings, consider adding a Quietaire silencer and IP-rated accessories available in the Norgren ecosystem.
European and global automation projects typically require CE compliance, with safety and environmental protections addressed through standard industry practices. While this data set lists core specifications, verify applicable CE marks and any regional IP or SIL requirements during procurement.
The valve’s lever actuators provide durable, tactile control with straightforward field adjustments. Use the compatible accessories (fittings, silencers, tubing) to optimize airflow, minimize noise, and simplify spare-part planning, helping to reduce downtime and extend mean time between failures.
