Norgren S/666/106 Inline Valve - 3/2 NC G1/8, Pneumatic
Part Number: S/666/106
Quick Summary
The S/666/106 Inline Valve is a compact, manual 3/2 valve designed for automated pneumatic circuits. Engineers often struggle with limited panel space and aligning actuation with sensors in tight installations. While the Martonair family is known for long-standing reliability, this unit operates across -20 to 80 °C and 2 to 10 bar, with a G1/8 port for straightforward plumbing. Its rod/spring return actuation delivers predictable fail-safe behavior in constrained spaces, reducing misfeeds and false actuation. From a procurement perspective, the valve integrates with standard Pneufit C fittings and common tubing, supporting easy stocking, faster maintenance, and scalable automation deployments. This combination delivers both operational precision and business value across industrial environments.

FAQs
For streamlined installation, use Pneufit C push-in fittings (example C02250618) with 6 mm tubing and G1/8 ports. The included PA tubing options (PA2-0006025C and PA2-0006100) support 6 mm/4 mm lines. A quiet operation can be achieved with a suitable silencer such as T40C1800 if noise reduction is required in the panel enclosure. This setup simplifies routing and reduces leak paths, speeding commissioning and maintenance.
The S/666/106 uses a G1/8 port, supports an operating pressure range of 2 to 10 bar (29 to 145 psi), and operates from -20 to 80 °C (-4 to 176 °F). These specs enable reliable performance across typical factory pneumatic lines and ambient conditions, while maintaining compact form factor for space-constrained panels.
Yes. Its compact dimensions (75 × 34 × 19 mm) and light weight (0.3 kg) fit tight spaces, making it suitable for packaging, assembly, and benchtop automation. The 3/2 NC configuration with rod/spring return provides a simple, fail-safe operation ideal for direct actuation and basic sequencing without requiring complex pilot circuitry.
The product data provided does not specify individual certifications. In European applications, verify CE marking and system-level safety assessments (including SIL considerations where applicable). Always consult the datasheet and supplier for the latest compliance documentation and ensure your integration meets your industry’s regulatory requirements.
Leverage the valve’s compatible fittings, tubing, and silencers to minimize leak paths and noise, reducing maintenance cycles. Standardized porting and readily available spare parts from Pneufit C and Norgren accessories simplify stocking and replacement, lowering downtime and total cost of ownership in automation lines.
