Sun Hydraulics 1HG4-AA Hydraulic Manifold Assembly

Sun Hydraulics 1HG4-AA Hydraulic Manifold Assembly is a member of Sun's ECT family, identified by the model code 1HG4-AA. This manifold assembly consolidates multiple valve cavities into a single housing, providing a centralized interface for hydraulic flow in cartridge-based Sun systems. By organizing inlet and outlet paths within one block, it supports compact hydraulic circuits used in industrial machinery and automated equipment. The 1HG4-AA designation denotes a specific configuration within Sun's manifold lineup, representing a predefined cavity layout and port arrangement that matches Sun’s footprint for compatible valves. The assembly is designed to integrate with Sun cartridge valves to streamline plumbing, improve mounting rigidity, and facilitate service when replacing cartridges or performing maintenance. In practice, using a Sun manifold centralizes feed and return connections and aligns with Sun’s standard valve footprints, making it suitable for circuits that require a compact, modular control block. Because 1HG4-AA is a fixed configuration within the ECT series, exact details such as cavity count, port sizes, and material finishes are defined by Sun Hydraulics for this model. For precise specifications, refer to Sun’s official documentation or an authorized distributor to ensure correct fitment in your hydraulic system.
