The Sun Hydraulics WQN (Material Number: WQN) is a motor mount manifold designed to facilitate the control and protection of hydraulic motors. This product features a Danfoss OMS interface, making it compatible with Danfoss OMS motors. The body of the manifold includes cross pilot capabilities on A with shuttle, providing enhanced functionality in hydraulic systems. The open cavities are labeled as 11, and it utilizes a T-2A cavity type. The port size is specified as SAE 10, ensuring standard connectivity within hydraulic applications. Constructed from 6061-T651 aluminum, the WQN manifold offers a balance between strength and corrosion resistance without the need for anodizing, which can reduce fatigue life by up to 50%. This aluminum alloy is chosen for its availability in various shapes and sizes and its ability to withstand corrosive environments effectively. Despite being relatively strong and inexpensive, it does not undergo anodization due to reasons such as increased cost and potential issues with stamping and inspection. When using this manifold, it is crucial to consider the maximum system pressure; manifolds made from aluminum should not exceed pressures of 3000 psi (210 bar). This product is ideal for applications requiring robust motor mounting solutions while maintaining operational efficiency in hydraulic circuits.

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.
