Overview of AMI Spool Options

The AMI Spool Options constitute a range of essential accessories for directional control valves in the hydraulic and fluid control sector. As reported in technical catalogue no. 205, these options make it possible to configure directional control valves according to specific operational needs by directly adapting the characteristics of the spool.

Flow Regulation and Control

Within the technical lineup, various configurations focused on fluid modulation are available to ensure maximum operational precision:

Model H24 is a spool specially engineered to provide a large positive overlap.
Model H25 is characterized as a metered spool, ideal for specific flow control requirements.
Model H25A is a dedicated metered spool variant, specifically sized to handle flow rates up to 15 l/min.

Spool Surface Treatments

To meet the demands of high mechanical strength, durability, and wear protection in hydraulic systems, the range offers options with different high-quality surface treatments:

Option H26 designates the nickel-plated spool.
Option H26T represents the spool subjected to a dual advanced technical treatment: it is both hardened and nickel-plated.
Finally, option H28 offers the chrome-plated spool solution.
