The Sun Hydraulics X3DNLANXA (Material Number: X3DNLANXA) is a versatile hydraulic assembly featuring a needle valve designed for precise flow regulation. This component serves as a fully adjustable orifice, allowing for infinite adjustments from fully closed to its maximum orifice diameter. It can be employed as both a flow control and shutoff valve, although it is not pressure-compensated. The valve's rapid or feed rate is controlled by a solenoid-operated, normally open or closed 2-way, 2-position valve, making it suitable for applications requiring variable flow rates. The needle valve's sharp-edged orifice design minimizes flow variations due to changes in fluid viscosity, ensuring consistent performance across different operating conditions. A balanced adjustment mechanism facilitates easy adjustments even under high-pressure scenarios. As a non-compensating device, the fixed orifice size regulates flow in proportion to the square root of the pressure differential between ports 1 and 2. This assembly has a capacity of 30 gpm (120 L/min) and features a sandwich body type with an ISO 05 interface. The meter-out T body feature and stack height of 2.49 inches (63 mm) make it compact yet efficient for integration into various hydraulic systems. A seal plate is included as part of the assembly. Constructed from corrosion-resistant 6061-T651 aluminum alloy, this needle valve assembly offers durability without compromising on weight. While anodizing could potentially enhance corrosion resistance further, Sun Hydraulics opts not to anodize their aluminum bodies due to cost considerations and potential impacts on fatigue life. The manifold's pressure rating should be carefully considered in relation to system requirements, as aluminum manifolds are not rated for pressures exceeding 3000 psi (210 bar).

Description

This assembly consists of a needle valve which is a fully-adjustable orifice used to regulate flow. It is infinitely adjustable from fully closed up to the maximum orifice diameter. It is not pressure-compensated. It may be used as flow controls or as shutoff valves. The rapid or feed rate is selected by a solenoid operated (normally open or closed) 2-way, 2-position valve.

The sharp-edged orifice design minimizes flow variations due to viscosity changes.
A balanced adjustment mechanism allows for easy adjustment even at high pressures.
Because needle valves are non-compensating devices, the fixed orifice size will regulate flow through the valve in proportion to the square root of the pressure differential across ports 1 and 2.

Show FAQ

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%.
Direct acting or pilot operated - what do I use?	Direct-acting valves are used to prevent over pressure, and pilot-operated valves are used to regulate pressure. If you are unsure, use a direct-acting valve. Sun's direct acting valves are very fast, dirt tolerant, stable, and robust. Sun's pilot-operated valves are moderately fast, they have a low pressure rise vs. flow curve, and they are easy to adjust.
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.

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.
