The Sun Hydraulics WPY (Material Number: WPY) is a line mount hydraulic manifold designed for inline and cross pilot applications. This manifold features a robust construction with a body type that supports none interface, ensuring compatibility with various hydraulic systems. It incorporates two mounting holes with a diameter of 0.34 inches (8.6 mm) and a through depth, accommodating secure installation with two mounting hole quantities. The manifold includes one open cavity, identified as T-2A, and is equipped with port sizes of 12 BSPP, making it suitable for specific hydraulic connections. Manufactured from 6061-T651 aluminum, the WPY manifold offers excellent corrosion resistance without the need for anodizing, which can compromise the fatigue life of aluminum manifolds by inducing cracks under pressure. This material choice ensures durability in various environmental conditions while maintaining cost-effectiveness and ease of machining. The design supports high flow valves and is compatible with Sun\u2019s floating style screw-in cartridges. The Sun Hydraulics WPY manifold is ideal for applications requiring reliable fluid distribution in hydraulic systems operating at pressures up to 3000 psi (210 bar). Its design accommodates precise hydraulic control in both industrial and mobile machinery environments where robust performance and longevity are crucial.

Show FAQ

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%.
How big is a drop of hydraulic oil?	There are exactly 250 Sun drops in a cubic inch or 15 in a cc.

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.
