The Sun Hydraulics A4H (A4H) is a versatile manifold specifically designed for use with solenoid-operated and electroproportional cartridges. This line-mount body type features a dual cavity that accommodates both standard and weatherized coils, ensuring flexibility in various applications. The manifold incorporates additional material around the cavity to provide necessary coil clearance along with the spotface needed for Sun's weatherized coil, enhancing its durability and performance in demanding environments. With a mounting hole diameter of 0.34 inches (8.6 mm) and a through-depth design, it offers secure installation with two mounting holes available for robust attachment. The manifold supports SAE 4 port size, making it compatible with standard hydraulic systems. Constructed from 6061T651 aluminum, this manifold is known for its relatively strong yet lightweight properties, excellent corrosion resistance, and cost-effectiveness. Despite being difficult to machine compared to other alloys, this material choice ensures longevity and reliability under various conditions without the need for anodizing processes that can compromise fatigue life or introduce inconsistencies in appearance. The A4H manifold\u2019s open cavities are designed to fit T-13A cartridges, providing compatibility with a range of hydraulic configurations. Its thoughtful engineering allows it to serve as an efficient component in hydraulic circuits where precise control of fluid flow is critical. Ideal for applications requiring robust performance in harsh environments, this manifold stands out due to its ability to maintain operational integrity without additional surface treatments like anodizing that could affect its structural integrity over time.
