The Sun Hydraulics ZZY (Material Number: ZZY) is a versatile line mount manifold designed for hydraulic systems. This component features a special 4-bolt interface for direct mounting, ensuring secure and stable installation. The manifold is crafted from 6061T651 aluminum, known for its excellent corrosion resistance and cost-effectiveness. It includes four mounting holes with a diameter of .41 inches (10.4 mm) and counterbore specifications of .59 inches (15.0 mm) in diameter and .47 inches (12 mm) in depth, allowing for easy integration into existing systems. The ZZY model accommodates one open cavity, identified as T3A, and is equipped with a 1 NPTF port size, suitable for various hydraulic applications. This manifold is particularly suited for high-flow valve applications due to its robust construction and compatibility with standard line mount manifolds. Users should be mindful of the maximum system pressure, as the aluminum construction limits the pressure rating to 3000 psi (210 bar). The design considerations ensure optimal performance while maintaining structural integrity under specified conditions. The Sun Hydraulics ZZY manifold does not undergo anodization due to potential drawbacks such as increased cost, logistics challenges, and reduced fatigue life associated with anodized aluminum surfaces. This decision enhances the longevity of the manifold by avoiding fatigue cracks that could compromise performance under pressure. Overall, the Sun Hydraulics ZZY model provides reliable performance in hydraulic systems requiring efficient fluid management through its thoughtfully engineered design tailored to meet specific operational needs without compromising on durability or functionality.

Show FAQ

How big is a drop of hydraulic oil?	There are exactly 250 Sun drops in a cubic inch or 15 in a cc.
Why does Sun use 6061 aluminum?	6061-T651 is relatively strong, relatively inexpensive, difficult to machine, readily available in all shapes and sizes and very corrosion resistant. 2024 is stronger and machines beautifully, but is expensive and falls to pieces in a corrosive environment.
Why doesn't Sun anodize their aluminum bodies?	Reasons to anodize: To increase corrosion resistance. Sun uses 6061-T651 aluminum. It is one of the most corrosion resistant aluminum alloys there is. Whether or not anodizing improves the corrosion resistance of 6061 aluminum is debatable. We have yet to have a manifold returned because of corrosion. Appearance (color). The 2 colors that would appeal to Sun would be blue or black. Unfortunately these are the colors that are hardest to do consistently. To provide a hard wear surface. Sun does not make parts-in-body valves. The manifold is just plumbing. We don't need a wear surface. Because everyone else does it. Bad reason. Reasons to not anodize: Cost. It's another process. Logistics. When you make tens of thousands of manifolds a month and you anodize hundreds, it's a problem. Consistency. See above. Stamping. After a body is anodized you cannot do any more stamping without making a mess.Inspection. Have you ever tried to look for burrs in a black anodized body? It's the old blackboard factory at night scenario. Torque. You will experience an increase in breakaway torque when removing items from an anodized manifold. Fatigue life. This is the best reason to not anodize. Fatigue failure is a very complex phenomenon. What it takes to initiate a crack is difficult to predict. What it takes to propagate a crack is readily defined. Anodizing produces a very thin, very hard, and very brittle surface on aluminum. The first time you pressurize an anodized aluminum manifold you have initiated fatigue cracks. Whether or not the stress is enough to propagate the cracks is a matter of pressure and manifold geometry. Anodizing an aluminum manifold grossly reduces the fatigue life by anywhere from 20% to 50%.

Notes:

Important: Carefully consider the maximum system pressure. The pressure rating of the manifold is dependent on the manifold material, with the port type/size a secondary consideration. Manifolds constructed of aluminum are not rated for pressures higher than 3000 psi (210 bar), regardless of the port type/size specified.
