The Sun Hydraulics W9K/S (Material Number: W9K/S) is a line mount manifold specifically designed for hydraulic applications, featuring a ninety-degree body configuration. This component includes eleven mounting holes with a diameter of 0.34 inches (8.6 mm), all of which are through holes to facilitate secure installation. The manifold also has eleven open cavities and utilizes the T13A cavity type, providing versatility in hydraulic circuit design. It is equipped with M14 x 1.56H port sizes, making it compatible with various hydraulic systems and components. Constructed from 6061T651 aluminum, the manifold offers excellent corrosion resistance without the need for anodizing, which can sometimes compromise fatigue life due to the brittle surface it creates on aluminum products. This material choice ensures durability and reliability under operating conditions up to a maximum system pressure of 3000 psi (210 bar), as long as the port size and type are appropriately matched. The Sun Hydraulics W9K/S is ideal for use in environments where robust performance and long service life are crucial, providing an efficient solution for managing high-flow valves within hydraulic systems. Its design considerations make it suitable for applications requiring reliable fluid management without unnecessary wear or maintenance challenges associated with anodized components.

Show FAQ

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%.
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.

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.
