The Sun Hydraulics WQQ/Y (Material Number: WQQ/Y) is a meticulously engineered motor mount manifold designed for interfacing with Danfoss OMS motors. This product features a cross pilot with shuttle body type, offering enhanced control and protection for hydraulic motors. It includes critical specifications such as a mounting hole diameter of 0.42 inches (10.7 mm), a mounting hole counterbore diameter of 0.69 inches (17.5 mm), and a depth of 0.43 inches (11.0 mm). The manifold is equipped with 22 open cavities and utilizes the T-2A cavity specification, with port sizes conforming to SAE 10 standards. Constructed from 6061-T651 aluminum, the manifold offers excellent corrosion resistance without the need for anodizing, making it suitable for various environments while maintaining structural integrity under operating pressures up to 3000 psi (210 bar). The design ensures easy installation and maintenance due to its through-hole mounting feature, accommodating diverse application needs in hydraulic systems. This component is ideal for use in systems where reliable motor control and protection are paramount, providing seamless integration into existing setups thanks to its compatibility with standard motor interfaces and port sizes. The careful consideration of material properties ensures long-lasting performance even under demanding conditions, making the Sun Hydraulics WQQ/Y an optimal choice for enhancing hydraulic motor efficiency and durability.

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:

Port S is the external connection in the end of the shuttle cartridge.
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.
