FAQs
This valve uses a DN15 port size with a 15 mm nominal diameter, enabling straightforward integration into standard pneumatic manifolds and compact automation stations. When planning installation, verify compatible manifold blocks and compatible seat seals (NBR) to maintain leak-tight performance across lifecycle. Proper alignment and flow-path orientation help minimize pressure drop and ensure repeatable actuation in production lines.
The 2/2 normally closed (NC) configuration provides a definitive shut-off when de-energized, reducing leakage paths and stabilizing actuations. In high-demand lines, this translates to faster return-to-seat behavior and lower energy waste per cycle. For best results, pair with clean, dry compressed air and correct filtration to maintain consistent response times and valve life.
The specification set indicates compatibility with CE standards and IP-rated options where applicable, supporting compliance in European and rugged environments. Always consult the attached datasheet and installation guide for exact IP rating and certification scope per configuration, and confirm with your systems integrator to ensure alignment with your plant’s safety and regulatory requirements.
NBR seat seals provide good abrasion resistance and oil compatibility for typical pneumatic service. To maximize seal life, ensure clean air supply, proper lubrication per manufacturer guidance, and periodic inspection during scheduled maintenance. If leakage or seat wear is observed, replace seals in accordance with the installation guide to restore peak performance without disassembling entire manifolds.
Expected ROI comes from reduced leakage, longer seal life, and lower downtime due to rugged cast steel construction and reliable NC operation. The DN15 port size enables quick retrofits into existing systems, shortening project timelines. Combined with standardization via the 86500 range, this valve simplifies spare parts management and supports consistent performance across multi-site deployments.
