The Sun Hydraulics B4K (Material Number: B4K) is a specialized hydraulic component designed for line mounting applications. This product features a ninety-degree configuration with a reverse flow check reducing capability, making it ideal for systems requiring precise flow control and pressure regulation. The body type is line mount with no specific interface requirements, allowing for versatile integration into various hydraulic setups. The B4K model includes 22 mounting holes with a diameter of .42 inches (10.7 mm), drilled through for secure attachment and stability in demanding environments. It also accommodates one open cavity with the T2A specification, ensuring compatibility with other Sun Hydraulics components. The port size is SAE 10, which supports standard connections in hydraulic circuits. Constructed from 6061T651 aluminum, the B4K offers excellent corrosion resistance and durability without the need for anodizing, thereby maintaining structural integrity under repeated pressurization cycles. This choice of material ensures longevity and reliability even in corrosive environments, making it suitable for various applications where environmental factors are a concern. The product's design focuses on minimizing fatigue failure risks by avoiding anodization, thus preserving the manifold's fatigue life by preventing crack initiation under pressure. Overall, the Sun Hydraulics B4K is engineered to deliver robust performance in hydraulic systems that demand efficient flow management and reduced risk of material degradation over time. Its thoughtful design and material selection make it an ideal choice for professionals seeking reliable and long-lasting hydraulic solutions.

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%.
