The Sun Hydraulics U5Y (U5Y) is a versatile manifold specifically designed for use with solenoid-operated and electroproportional cartridges. This manifold features additional material around the cavity to accommodate coil clearance and includes the necessary spotface for Sun's weatherized coil. It is a line-mount body type, featuring a ninety-degree interface that accepts both standard and weatherized coils, making it adaptable for various hydraulic applications. The manifold has a mounting hole diameter of 0.34 inches (8.6 mm) and supports through-hole mounting with two holes available. It is equipped with one open cavity of the T31A type and utilizes SAE 10 port sizes, suitable for high-flow valve applications. Constructed from 6061T651 aluminum, the U5Y offers excellent corrosion resistance without the need for anodizing, which could compromise fatigue life due to the brittle surface it creates on aluminum. This material choice provides durability in corrosive environments while maintaining cost-effectiveness and availability in various forms. The manifold is not rated for pressures exceeding 3000 psi (210 bar), emphasizing the importance of considering maximum system pressure in its application to ensure safety and performance. The U5Y manifold serves as an efficient plumbing solution in hydraulic systems where solenoid-operated or electroproportional control is required, providing reliable performance without compromising on structural integrity or longevity under specified pressure limits.

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.
