AMI Spool Control
The AMI Spool Control represents an advanced technical solution for actuating hydraulic directional control valves. Available in multiple 2, 3, and 4-position configurations, it provides reliable systems through spring return to center, mechanical detents, and floating positions. The series covers a wide range of directional valves, ensuring operational precision for complex hydraulic circuits and high efficiency standards. The available product codes (actuation models) are: C1, C2, C3, C4, C5
The AMI Spool Control range includes multiple options for operating hydraulic directional control valves. The systems are designed to manage hydraulic flow through the use of 2, 3, or 4-position spools, adapting to the specific requirements of hydraulic circuits. Among the main 3-position variants, there are spring-centered configurations (C1 series), essential for operations where immediate return to neutral is required upon release. When stability in specific positions is needed, models C2, C3, and C4 offer spring centering combined with mechanical detents in positions 1 and 2, in position 1 only, or in position 2 only, respectively. For applications requiring greater operational flexibility, the 4-position versions (C5 and C5S) integrate spring centering with a detent in the fourth floating position, available in both pull and push variants.
In addition to standard models, AMI Spool Control provides advanced detent systems to hold the spool in desired positions without continuous operator input. Model C6 provides detents in all 3 operating positions, while models C7 and C8 provide detents in 2 positions (1 and 0 for C7; 2 and 0 for C8). Models C13 and C14 complete the mechanical detent lineup: C13 provides stable locking across all 4 operating positions, ideal for machinery requiring continuous work cycles; C14 focuses on simpler 2-position configurations, with detents in 1 and 2.
Regarding spring return, the series offers specifically calibrated actuations: version C9 provides spring return to position 2, and C10 to position 1. Variants such as C10A and C11/C11SPD manage spring return unidirectionally between positions 0 and 1, while C12 manages spring return to position 0 starting from position 2. Complex 4-position systems such as C15 and C15S combine spring return to center from specific positions with a detent in the fourth floating position, ensuring differentiated control of the directional valve.
AMI Spool Control systems are designed as accessories for an extensive line of hydraulic directional control valves, whose codes identify direct mounting compatibility. Supported families include models AMI 3, AMI 4, AMI 5C, AMI 12C, AMI 012, AMI 013, AMI 21R, AMI 42C, AMI 130, AMI 250, AMI 300, and AMI 700. Each spool control features a specific dimensional footprint (longitudinal dimension value indicated in the technical catalog) that varies depending on the directional valve size and the complexity of the internal mechanism. The highlighted configurations demonstrate the full versatility of the series, covering all system needs from low to high flow rates.
