The Sun Hydraulics VYB (VYB) is a versatile hydraulic component designed for gasket mount applications. Featuring a direct mount, cross pilot configuration with two gasket ports, it is engineered for reliability and ease of use. The VYB model accommodates 38 NPTF port sizes and requires three mounting holes with a diameter of 0.41 inches (10.4 mm) that extend through the body, complemented by a counterbore diameter of 0.59 inches (15.0 mm). This component is constructed with open cavities in a T2A cavity design, ensuring compatibility and flexibility in various hydraulic systems. Manufactured from 6061-T651 aluminum, the VYB offers excellent corrosion resistance without the need for anodizing, which can reduce fatigue life due to crack initiation under pressure. This choice of material ensures durability and long-term performance under pressures up to 3000 psi (210 bar), making it suitable for moderate-pressure hydraulic applications. The design considerations include careful attention to system pressure limitations based on material properties, ensuring that users do not exceed recommended pressure ratings to maintain system integrity and safety. The Sun Hydraulics VYB is ideal for those seeking a robust and reliable manifold solution within its specified operational parameters.

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.
