V 04-3859-03: SPOOL, AIR CONTROL, PS4-8 – A precision-machined, multi-groove internal air control spool component built for PS4 and PS8 series air motors. It shifts back and forth under pressure to alternate airflow pathways between diaphragm chambers.

V 04-3859-03: SPOOL, AIR CONTROL, PS4-8 – A precision-machined, multi-groove internal air control spool component built for PS4 and PS8 series air motors. It shifts back and forth under pressure to alternate airflow pathways between diaphragm chambers.

Key Features
  1. Specialized air control (AIR CONTROL) steering spool engineered to alternate main pressurized airflow ports smoothly.
  2. Sized precisely for PS4-8 series pneumatic blocks to guarantee sharp, stall-free pump stroke cycling transitions.
  3. Minimized internal clear tolerances eliminate high-pressure signal bleed paths inside the manifold tracking lines.
  4. Robust core build handles standard factory compressed air lines without sticky residue sticking or timing lag faults.
  5. Pre-fitted sliding lands reduce startup friction thresholds to maximize overall pneumatic motor power metrics.
