The Sun Hydraulics X3DXXANXA/S (X3DXXANXA/S) is a sophisticated flow control valve assembly designed for precise flow regulation in hydraulic systems. This unit integrates a fixed-orifice, pressure-compensated flow control valve, enabling accurate meter-in or meter-out applications even under varying pressure conditions. The flow rate is factory-set based on user specifications and can be adjusted by \u00b125% from the nominal preset by turning the adjustment clockwise. A solenoid-operated, two-way, two-position valve allows selection between rapid or feed rates, providing versatile operation modes. The sharp-edged orifice design effectively minimizes flow variations caused by changes in fluid viscosity, ensuring consistent performance. Users must specify the desired flow rating at the time of order, with factory settings accurate within \u00b110% of the requested value. The assembly has a capacity of 30 gallons per minute (120 liters per minute) and features a sandwich body type with an ISO 05 interface and a stack height of 2.49 inches (63 mm). It includes a seal plate as standard. This model is particularly suitable for applications requiring reliable and adjustable flow control in hydraulic circuits where pressure fluctuations are common. Its robust construction and precise regulation capabilities make it an ideal choice for maintaining system stability and efficiency.

Description

This assembly consists of a fixed-orifice, pressure-compensated flow control valve which provides precise flow regulation for meter-in or meter-out applications where there may be wide pressure fluctuations. The flow setting is specified by the user and is set at the factory. 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.
The tuneable control option provides +/- 25% variation from the nominal factory pre-set flow. Turn the adjustment clockwise to increase.
Customer must specify a flow rating. Factory set flow ratings are within +/- 10% of the requested setting.

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.
