The Sun Hydraulics ZQA (Material Number: ZQA) is a precision-engineered hydraulic manifold designed for efficient fluid control in various hydraulic systems. This model features a line mount interface with a 1.50 SAE C61 specification, ensuring compatibility with standard hydraulic components. The body of the ZQA is designed for sandwich mounting through ports, allowing for streamlined integration into existing systems. It includes open cavities type 11 and utilizes the T16A cavity configuration, making it versatile for different hydraulic applications. The port size is specified as 1 1/2 Code 61, providing ample flow capacity for high-demand operations. Constructed from 6061-T651 aluminum, this manifold offers excellent corrosion resistance and durability while being lightweight and cost-effective. Despite its robust construction, it is not anodized to maintain the material's natural fatigue life and avoid issues related to increased breakaway torque or inspection difficulties associated with anodized surfaces. It is important to note that this manifold is rated for a maximum system pressure of up to 3000 psi (210 bar), making it suitable for medium-pressure applications. The Sun Hydraulics ZQA model is ideal for use in systems where reliable fluid distribution and control are critical. Its design facilitates easy integration into complex hydraulic circuits while maintaining system integrity and performance. Whether used in mobile equipment or industrial machinery, this manifold provides dependable service by efficiently managing hydraulic fluid flow within the specified pressure limits.

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.
