FAQ
▔▔Q: How can I confirm the exact model number for my system?
A: Check the nameplate on your existing valve for the full part code, or provide your machine manufacturer name, hydraulic schematic, and mounting dimensions.
Q: What is the recommended filtration precision for these servo valves?
A: To ensure optimal spool longevity and prevent contamination failures, we recommend a filtration rating of ISO 4406 16/14/11 or better (10 micron absolute or finer).
