How does the open center friction detent spool work on this valve?

Question by: Dustin M on May 16, 2025, 9:38 PM

The open center friction detent spool in the AO755 Series 1-Spool Monoblock Valve allows fluid to flow continuously when the spool is in the neutral position, making it suitable for applications requiring steady flow. The friction detent helps maintain the spool position, preventing accidental movement and ensuring reliable operation.
