Overview and Features of AMI Devices<\/h3>\n

The range of accessories designed for hydraulic directional control valves allows for customization and optimization of fluid directional control. Available solutions include reversing mechanisms, systems for converting the operating function, and hydraulic spool actuation units, supporting a wide variety of operating configurations. All options ensure precision and reliability within complex hydraulic circuits. <\/p>\n

Reversing (H20) and Conversion Devices (H49 – H50)<\/h3>\n

The H20 model operates as an automatic spool reversing device and is designed to work exclusively in combination with the C14 control. Overall dimensions vary depending on the selected directional control valve model: for AMI 3, AMI 4, AMI 250 and AMI 5C versions, the reference dimension is 92 mm, while for AMI 21R, AMI 300, AMI 130, AMI 700, AMI 42C and AMI 12C versions, it is 113 mm.<\/p>\n

To modify the type of actuation, the H49 and H50 devices allow conversion from double-acting to single-acting operation at ports A and B. Installation of these components requires a strict technical condition: the hydraulic directional control valve body must be specifically pre-configured. These devices are compatible with the entire range, including the specific AMI 012 and AMI 013 models.<\/p>\n

Hydraulic Spool Actuation Systems (H53, H53S, H53A)<\/h3>\n

The range includes several variants for hydraulic spool actuation, all equipped with hydraulic pilot ports featuring 1\/4″ BSP threads.<\/p>\n

The H53 device provides standard hydraulic control. Installation dimensions (A and B) are A=79 and B=79 for AMI 3, AMI 4, AMI 250 and AMI 5C models; A=72 and B=53 for AMI 21R, AMI 300 and AMI 130 versions; A=92 and B=53 for AMI 700, AMI 42C and AMI 12C series.<\/p>\n

The H53S variant is intended for systems where flow rate is reduced, and its use in combination with the H25 metered spool is strongly recommended. In this configuration, dimensions are A=79 and B=79 (AMI 3, AMI 4, AMI 250, AMI 5C) or A=53 and B=53 (AMI 21R, AMI 300, AMI 130, AMI 700, AMI 42C, AMI 12C). For models supported by the H53S version, the directional control valve body always requires specific structural preparation.<\/p>\n

The H53A option provides hydraulic spool actuation with vertically arranged 1\/4″ BSP connections. As with the H53S model, use with the H25 metered spool is recommended due to the reduced flow rate. Dimensions for compatible valves (AMI 3, AMI 4, AMI 250, AMI 5C) are A=58 and B=58.<\/p>\n

Electrical Safety Lock Kits (H90 – H91)<\/h3>\n

For critical applications requiring the spool to be immobilized under maximum safety conditions, the range includes the H90 and H91 electrical kits. The H90 unit is designed for a 12V DC power supply, while the H91 model operates in 24V DC systems. Both mechanisms ensure complete locking of the spool position and can be installed across almost all AMI models available in the catalogue. <\/p>\n
