Application-Specific Design for Space-Constrained Pneumatics
The Festo VABS-K2-10S-16-G18-P sub-base (part no. 8186874) is engineered for single-valve stations where mounting space is at a premium. With a nominal width of 1.6 mm and a valve size of 10 mm, this compact unit suits precise, low-flow pneumatic control tasks in assembly fixtures, test rigs, and small-format automation modules. Its side connection direction simplifies tubing routing in tight panels, while the through-hole mounting method allows direct fastening to machine frames or manifold blocks without additional brackets.
The sub-base accepts valves with internal thread mounting and provides a G1/8 fluid connector. This standardized port simplifies integration with common fittings and tubing, reducing the need for adapters. The non-reversible flow direction is clearly defined, ensuring predictable media routing during system design.
Material and Media Compatibility Considerations
The sub-base is machined from PEEK, a high-performance polymer known for dimensional stability and broad chemical resistance. This material choice, combined with a corrosion resistance class (CRC) of 0, makes the unit suitable for environments with no corrosive stress. The product is RoHS-compliant and conforms to VDMA24364 zone III for LABS (PWIS) freedom, which is critical for paint shops and coating lines where silicone contamination must be avoided.
Both liquid and gaseous media can be handled, but the operating temperature range is limited to 0°C to 50°C for the medium and ambient air. Storage temperature spans from -20°C to 70°C. Always verify that the media's chemical compatibility with PEEK and any sealing materials meets your process requirements, as the manufacturer advises checking resistance of all contact materials.
Mounting Flexibility and Torque Specifications
One of the key advantages of this sub-base is its ability to be mounted in any orientation, giving designers freedom to position valves for optimal service access or gravity-independent operation. The unit is secured using through-holes, and the maximum tightening torque for the sub-base itself is 0.6 Nm. When mounting the valve onto the sub-base, do not exceed 0.2 Nm, as over-tightening can damage the threads or distort the sealing surfaces.
For pneumatic fittings connected to the G1/8 port, the maximum tightening torque is 7 Nm. Adhering to these limits prevents thread galling and ensures leak-free connections over the product's service life. The sub-base weighs only 20 g, adding negligible mass to moving or cantilevered assemblies.
Integration with Festo System Components
Designed as part of the Festo range, this sub-base is intended to work seamlessly with Festo valves of the corresponding size and mounting pattern. This compatibility simplifies procurement and reduces engineering risk, as the interface dimensions and sealing characteristics are matched to Festo's valve portfolio. For maintenance or reconfiguration, the single-valve design (max. one valve position) allows quick replacement without disturbing adjacent pneumatic circuits.
When planning your pneumatic layout, consider that the sub-base is not reversible in flow direction, so confirm the valve's flow path matches your application. The product is suitable for food industry use only after consulting supplementary material information, so verify compliance with your specific hygiene standards before deployment.
Practical Benefits for System Builders
For engineers and procurement teams, the VABS-K2-10S-16-G18-P offers a balance of compactness, material performance, and installation ease. Its PEEK construction provides long-term reliability in demanding industrial environments, while the low weight and small footprint contribute to lean machine designs. The clear torque specifications and mounting guidelines reduce assembly errors, and the LABS conformity avoids costly contamination issues in coating processes.
Whether you are designing a new pneumatic circuit or retrofitting an existing one, this sub-base delivers a dependable foundation for single-valve control points. Its compatibility with standard G1/8 fittings and Festo valves streamlines sourcing and assembly, making it a practical choice for applications that require precise, space-efficient fluid control.
