The Sun Hydraulics WNM/S (WNM/S) is a line mount hydraulic manifold designed with a bypass compensator, making it suitable for various hydraulic applications requiring efficient fluid control. This model features a body type that is specifically tailored for line mounting, with no additional interface required. It includes a .375-16 UNC 2B in. mounting hole thread and a depth of .62 in., with two mounting holes available for secure installation. The manifold is constructed to accommodate open cavities, specifically T16A, and is equipped with SAE 16 port sizes to ensure compatibility with standard hydraulic systems. Designed for robustness and durability, the WNM/S model leverages the use of 6061-T651 aluminum due to its strength, cost-effectiveness, and excellent corrosion resistance properties. Although anodizing could enhance corrosion resistance further, Sun Hydraulics opts not to anodize this model due to potential drawbacks such as increased cost and reduced fatigue life of the material. The manifold's construction ensures it can withstand maximum system pressures up to 3000 psi (210 bar), as long as the appropriate considerations regarding manifold material and port size are taken into account. This hydraulic manifold is ideal for applications that demand reliable performance in fluid control without compromising on structural integrity under pressure conditions typical of standard industrial environments.

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.
