2) Cons

• Long Lead Times for Highly Custom Orders: Tailored engineering and stringent testing can extend lead times compared to off-the-shelf valve suppliers.
• Higher Unit Costs for Low-Volume Runs: Premium materials and precision manufacturing often mean higher minimum order quantities and per-piece costs for small projects.
• Geographical Concentration: Most production is centered in specific German regions; logistical planning is essential for large or time-sensitive shipments outside Europe.
• Complexity of Product Range: Extensive portfolios and technical specifications can be overwhelming without expert guidance, necessitating early engagement with manufacturer sales engineers.
• Language & Cultural Barriers: While many firms operate globally, technical documentation and communications may still default to German, requiring bilingual coordination for international clients.
