The Sun Hydraulics X4DDLANXA (Material Number: X4DDLANXA) is a versatile assembly designed for precise flow regulation in hydraulic systems. It features a fully adjustable, pressure-compensated flow control with a reverse-flow check, making it suitable for meter-in or meter-out applications that experience wide pressure fluctuations. This unit allows infinite adjustment from nearly closed to maximum flow, providing flexibility in various operational settings. An integral high-capacity check valve ensures unrestricted flow in the reverse direction, enhancing system efficiency and performance. The assembly incorporates a solenoid-operated, normally open or closed 2-way, 2-position valve to select rapid or feed rate changes. The sharp-edged orifice design minimizes flow variations due to changes in fluid viscosity, while the balanced adjustment mechanism facilitates easy adjustments even under high-pressure conditions. With a capacity of 30 gallons per minute (120 liters per minute), this sandwich-type body is compatible with ISO 05 interface standards and offers meter-in on port A or meter-out on port B functionalities. The stack height of the assembly is 2.99 inches (76 mm), and it includes a seal plate as noted in the specifications. This assembly is constructed using durable materials like 6061-T651 aluminum, known for its excellent corrosion resistance and structural integrity under pressure up to 3000 psi (210 bar). Such characteristics make it ideal for applications requiring reliable performance under varying pressure conditions without anodizing. This product is particularly suited for scenarios where precise control over hydraulic flow is critical, ensuring optimal operation across diverse applications.

Description

This assembly consists of a fully-adjustable, pressure-compensated flow control with reverse-flow check which provides precise flow regulation for meter-in or meter-out applications where there may be wide pressure fluctuations. It is infinitely adjustable from nearly closed up to the maximum flow. An integral high-capacity check valve provides unrestricted flow in the reverse direction. 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.

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:

Stack height value in technical data table includes seal retainer plate.
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.
