The Sun Hydraulics VML (Material Number: VML) is a versatile aluminum bar manifold designed for hydraulic applications. This model features a 3-station, parallel circuit configuration with a relief cavity, making it suitable for systems requiring efficient fluid distribution and pressure management. The manifold is built to the ISO 05 XY US interface standard, ensuring compatibility with various hydraulic components. It includes four mounting holes threaded at .375-16 UNC 2B with a depth of .75 inches, providing secure installation options. Additionally, the manifold has one open cavity and uses SAE 12 port sizes for fluid connections. Constructed from corrosion-resistant 6061-T651 aluminum, the VML manifold offers durability and reliability in demanding environments. However, it is important to note that this material limits the maximum pressure rating to 3000 psi (210 bar). This makes it essential to consider system pressure requirements when integrating the manifold into your hydraulic setup. The robust design of the VML model ensures effective performance in managing hydraulic flow and maintaining system integrity under specified conditions.

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.

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.
