The Sun Hydraulics EIK (Material Number: EIK) is a specialized manifold designed for use with direct-acting sequence valves featuring a reverse-flow check. This line-mount manifold is crafted to accommodate a 2-cylinder sequence, ensuring efficient and reliable operation in hydraulic systems. It features two open cavities, designated as T11A, and is equipped with SAE 10 port sizes, providing compatibility with standard hydraulic fittings. The mounting holes are designed for through-hole installation, with a diameter of .34 inches (8.6 mm), and there are two such mounting points available. Constructed from 6061-T651 aluminum, this manifold offers excellent corrosion resistance without the need for anodizing, which can compromise fatigue life by introducing brittle surfaces prone to cracking under pressure. The material choice balances strength and cost-effectiveness while maintaining durability in various environments. It's important to note that this manifold is not rated for pressures exceeding 3000 psi (210 bar), so careful consideration of maximum system pressure is crucial during application planning. The Sun Hydraulics EIK manifold serves as an essential component in hydraulic systems requiring precise sequence control, particularly where reverse-flow prevention is critical. Its robust design and material selection make it suitable for demanding applications while ensuring long-term reliability and performance in managing fluid flow within hydraulic circuits.

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:

For use with direct-acting sequence valves with reverse-flow check
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.
