AMI Pre-arrangements
AMI Pre-arrangements are accessories for hydraulic directional control valves designed to optimize fluid control and integration in hydraulic systems. The range includes specific solutions for panel inlet and return, as well as pre-arrangements for mounting external and built-in auxiliary valves. Each technical variant is developed to ensure precise connections (P, T, A, B lines) and absolute application versatility. The available product codes are: AMI 3, AMI 4, AMI 21R, AMI 250, AMI 300, AMI 130, AMI 700, AMI 012, AMI 013, AMI 5C, AMI 42C, AMI 12C.
The AMI Pre-arrangements constitute a specialized range of accessories for hydraulic directional control valves, as detailed in Technical Catalogue no. 205. These components are essential for the correct configuration of complex hydraulic circuits. Designed to facilitate the integration and mounting of components in the circuits, these pre-arrangements ensure precise and secure connections for the operational management of pressure lines, return lines, and direct ports, as well as allowing the installation of various types of supplementary control valves.
The catalogue provides specific technical solutions for panel mounting positioned on the lower part of the directional control valve body. The configuration identified by the code H27 is strictly dedicated to the management of fluid inlet and return. Specifically, this technical variant pre-arranges the main pressure line (P) and the return line (T) for panel installation on the lower part of the body. At the same time, the variant named H32 focuses entirely on the system ports. This option allows the effective pre-arrangement of the connections for the port lines (identified with letters A-B) directly on the lower panel part of the valve body, ensuring an optimized operational interface for the entire hydraulic system.
The range of AMI Pre-arrangements also includes advanced configurations for the integration of auxiliary valves, whether external or built-in, designed to significantly extend the operational capabilities of the circuit. The H12 configuration provides a structural pre-arrangement for mounting external auxiliary valves, allowing the addition of external control functions to the main block. For control and safety needs, the H21 model provides a plugged pre-arrangement located directly on the working section. This technical solution is explicitly designed for the subsequent mounting of a pressure relief valve, specifically classified and identified as type Z50. Finally, the H22 technical variant offers a plugged pre-arrangement designed for housing and mounting built-in auxiliary valves (identified in the catalogue by the code Z6-27), ensuring high flexibility for the internal configurations of the valve body.
A fundamental advantage of these pre-arrangements is their absolute versatility within the catalogue. All the described technical configurations (H27, H32, H12, H21, H22) are uniformly compatible with an extensive and specific range of directional control valve models. The complete list of supported models for all pre-arrangement variants is as follows: AMI 3, AMI 4, AMI 21R, AMI 250, AMI 300, AMI 130, AMI 700, AMI 012, AMI 013, AMI 5C, AMI 42C, and AMI 12C. This extensive backward compatibility and integration certify the AMI Pre-arrangements as a reliable and highly scalable standard for the entire landscape of the listed directional control valves.
