The Sun Hydraulics FNI (FNI) is a line mount hydraulic manifold designed with a ninety-degree configuration and features a reverse flow check. It is constructed to accommodate SAE 6 port sizes, providing flexibility for various hydraulic applications. The manifold can be mounted using two holes, each with a diameter of .28 inches (7.1 mm), and these holes go through the entire body of the manifold, ensuring secure attachment in system assemblies. This model includes one open cavity and is compatible with the T10A cavity type, allowing integration with specific cartridge valves. The FNI model is crafted from 6061T651 aluminum, known for its balance of strength, cost-effectiveness, machinability, availability in diverse shapes and sizes, and excellent corrosion resistance. This choice of material ensures that the manifold can withstand harsh environments without succumbing to corrosion-related damage. However, it should be noted that this aluminum manifold is not rated for pressures exceeding 3000 psi (210 bar), regardless of the port size specified. This product does not undergo anodizing due to several reasons: additional cost, logistical challenges when manufacturing at scale, potential inconsistencies in appearance and quality control issues such as difficulty in inspecting anodized surfaces for burrs. Moreover, anodizing can significantly reduce fatigue life by initiating surface cracks under pressure due to its brittle nature. Overall, the Sun Hydraulics FNI line mount manifold offers robust performance in hydraulic systems where moderate pressure levels are maintained and provides reliable flow control through its integrated check valve feature.
