Feature: Compact dimensions and lightweight profile enable placement in tight automation panels. Business impact: Frees up space for additional flow control components, reducing overall system footprint and installation time. Application: Suitable for small machine bays where linear actuators are driven by 3/2 NO valves. Feature: G1/8 port size and 2–10 bar operating range provide versatile integration with standard pneumatic lines. Business impact: Broad compatibility minimizes rework when replacing older components; supports reliable actuation across common compressed air systems. Application: Ideal for inline valve banks in EU-manufactured equipment employing 6mm/4mm tubing. Feature: Roller/spring return actuation delivers quick, repeatable cycling and predictable timing. Business impact: Improves cycle accuracy and reduces setup time; lowers maintenance by simplifying return-to-home positioning. Application: Use in rapid sequencing of grippers and cylinders on assembly lines. Feature: 3/2 valve operation and NO configuration simplify logic and wiring. Business impact: Reduces control complexity and fault points; enhances fault diagnosis in automated loops. Application: Fits basic pneumatics control schemes where simple on/off actuation is required. Feature: Versatile fittings and silencers enable clean, quiet installations. Business impact: Minimizes leak paths and noise, improving operator comfort and compliance with workplace noise standards. Application: Integrates with Pneufit C fittings, T40C1800 silencers, and PA2 tubing for a complete, easy-to-service solution.

FAQs
For proper installation, choose the G1/8 port and use compatible Pneufit C push-in fittings (C02250618 or C02470618) with 6 mm tubing. Pair the valve with a T40C1800 silencer to minimize noise, and position the unit so 75 mm length and 34 mm width fit your control panel. Ensure secure mounting to prevent vibration.
The S/667/8 supports an operating pressure range of 2 to 10 bar and is actuated by a roller return with spring return. It is a 3/2 valve configured as normally open (NO) to provide straightforward actuation sequences in pneumatic circuits and reduce the risk of unintended actuation during maintenance.
Yes. Its compact dimensions (75 mm long, 34 mm wide, 19 mm high) and light weight (0.228 kg) make it ideal for inline valve banks in small automation manifolds. The G1/8 port size aligns with common piping, and the roller/spring mechanism supports reliable cycling in space-constrained panels.
Use Pneufit C push-in fittings (C02250618 or C02470618) for fast, leak-tight connections, and install a T40C1800 Quietaire silencer to reduce exhaust noise. For fluid routing, PA2 tubing is available in 100 m and 25 m reels (6 mm/4 mm). A tube cutter (M/3314) helps achieve clean, square cuts for leak-free joints.
