AMI Inlet Manifolds
AMI inlet manifolds are accessories for hydraulic directional control valves, designed to ensure optimal fluid management and control within the circuit. Available with right or left inlet orientation, they integrate modules such as the main relief valve, check valve, or replacement plug. Built for demanding applications, they guarantee complete compatibility with the main AMI series directional control valves.
The available product codes (model families) are: P1S, P2S, P3S, P4S, P1D, P2D, P3D, P4D.
The AMI Inlet Manifolds represent fundamental components classified as directional control valve accessories within hydraulic systems. Manufactured by Oleodinamica AMI, these manifolds serve as connection, distribution, and fluid management elements at the inlet of the valve assembly. The technical documentation defines a strictly structured range of manifolds, differentiated according to inlet flow orientation and the integration of specific valve groups. The use of AMI Inlet Manifolds is essential for configuring hydraulic circuits that require precise control of line pressure and operating fluid directionality, ensuring efficiency and structural reliability.
The technical lineup is divided into two primary families, strictly linked to the orientation of the hydraulic inlet. Left inlet manifolds are identified by models P1S, P2S, P3S, and P4S. In a mirrored layout, right inlet manifolds are classified by models P1D, P2D, P3D, and P4D. This clear engineering division enables system designers and testing technicians to configure the hydraulic system according to the spatial and layout constraints of the machine, while maintaining the high hydraulic control performance guaranteed by AMI components.
AMI Inlet Manifolds feature four specific hydraulic configurations for each orientation, covering all modulation requirements. The most complete configuration includes a main relief valve mechanically coupled with a check valve (combination Z26), implemented in models P1S and P1D. When circuit specifications only require maximum pressure limiting, variants equipped with a main relief valve only (option Z27) are used, available on models P2S and P2D. Should the design exclusively require backflow prevention while maintaining fluid direction, manifolds equipped with a check valve paired with a valve replacement plug (variant Z28) are provided, corresponding to models P3S and P3D. Finally, for custom applications where pressure and direction control are delegated to logic blocks external to the manifold, models provided exclusively with a valve replacement plug (code Z29) are installed, identified as P4S and P4D.
These inlet manifolds are accessories engineered and tested to interface natively with an extensive selection of hydraulic directional control valves in the AMI range. Technical tables certify complete coupling compatibility with the following directional valve series: 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. During hydraulic system sizing and validation, verifying coupling tolerances is essential: the manufacturer strictly specifies that directional control valve codes highlighted in grey within the catalogue datasheets are not available for the respective manifolds. This makes cross-referencing technical data indispensable prior to on-machine integration.
