The Sun Hydraulics BVA (Material Number: BVA) is a line-mounted hydraulic body, designed for inline applications. It features a mounting hole diameter of 0.34 inches (8.6 mm) and accommodates two mounting holes with a through-depth configuration. The body is equipped with one open cavity, specifically the T2A cavity, and offers a port size of 1/4 NPTF, making it suitable for various hydraulic systems requiring precise fluid control and management. The BVA model is crafted from 6061T651 aluminum, known for its strength, affordability, machinability, availability in diverse shapes and sizes, and excellent corrosion resistance. This choice of material ensures durability and longevity even in challenging environments without the need for anodization. The design considerations behind not anodizing the aluminum bodies include cost-effectiveness, logistical efficiency given the production volume, consistency in manufacturing processes, as well as factors related to inspection and torque management during assembly or maintenance. Notably, avoiding anodization also enhances the fatigue life of the manifold by reducing potential fatigue crack initiation and propagation under pressure. This product is particularly advantageous for applications where robust performance is required without compromising on material integrity due to environmental factors or operational stressors. The BVA model's specifications make it an ideal choice for systems that demand reliable operation with minimal maintenance intervention over time.

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%.
