FAQ
▔▔Q: How do I confirm the exact replacement model for my application?
A: Check the nameplate on your existing Atos valve for the full model code, or provide us with your machine brand, system pressure, and port size so our engineers can cross-reference the correct specification.
Q: What is the recommended oil filtration accuracy for these valves?
A: To ensure optimal longevity and prevent spool jamming, we recommend maintaining fluid cleanliness at ISO 4406 standard 18/16/13 or better, using a minimum 10-micron filter element.
