The Sun Hydraulics VYW (Material Number: VYW) is a precision-engineered hydraulic manifold designed for efficient fluid control in various applications. This model features a direct mount, cross pilot design with two gasket ports, and is constructed for gasket mounting with a mounting hole diameter of 0.41 inches (10.4 mm) and depth that goes through the entire body. The mounting hole has a counterbore diameter of 0.59 inches (15.0 mm), and the unit comes with three mounting holes to ensure secure installation. The VYW model accommodates open cavities in configurations of either two or three, and it utilizes the T-2A cavity standard for its construction. The port size is specified at 3/4 BSPP, which ensures compatibility with various hydraulic systems requiring British Standard Pipe Parallel threads. Constructed from 6061-T651 aluminum, this manifold offers excellent corrosion resistance without the need for anodizing, making it suitable for environments where durability and longevity are critical. Although not anodized, this choice of material provides a balance between strength and cost-effectiveness while maintaining high resistance to corrosive elements. One important consideration when using this manifold is the maximum system pressure; manifolds made from aluminum, such as this one, should not be used in applications exceeding 3000 psi (210 bar). This pressure rating ensures safe operation within specified limits while maintaining optimal performance. Overall, the Sun Hydraulics VYW model stands out for its robust construction and adaptability to various hydraulic applications where reliable fluid control is essential.

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.
