The Sun Hydraulics FNU (Material Number: FNU) is a specialized hydraulic component designed for line mounting applications. This product features a ninety-degree body type with a reverse flow check, making it ideal for systems that require controlled directional flow. The unit is designed to be mounted using two through holes, each with a diameter of 0.28 inches (7.1 mm), ensuring secure installation in various setups. It accommodates one open cavity and is compatible with the T10A cavity type, allowing for versatile integration into existing hydraulic systems. The FNU model includes a 3/8 BSPP port size, which is standard for many hydraulic applications, facilitating easy connection to other components within the system. The check cracking pressure of this model is set at 4 psi (0.3 bar), providing reliable performance in maintaining desired pressure levels and preventing backflow. Constructed from 6061 aluminum, the manifold offers excellent corrosion resistance without the need for anodizing, which can compromise fatigue life by introducing potential crack initiation sites during pressurization. This material choice ensures durability and longevity under typical operating conditions while keeping manufacturing costs manageable. It is important to note that manifolds made from aluminum are not rated for pressures exceeding 3000 psi (210 bar). Therefore, users should carefully consider their system's maximum pressure requirements when integrating this component to ensure safe and optimal operation.
