The Sun Hydraulics X7HDLANXA (Material Number: X7HDLANXA) is a versatile hydraulic assembly designed for precise flow regulation in meter-in or meter-out applications, particularly where there are significant pressure fluctuations. This assembly features a fully adjustable, pressure-compensated flow control with a reverse-flow check valve, allowing for consistent performance even under varying conditions. It is infinitely adjustable from nearly closed to the maximum flow capacity of 60 gpm (240 L/min). The integral high-capacity check valve ensures unrestricted flow in the reverse direction, enhancing its operational efficiency. The unit also incorporates a solenoid-operated, normally open or closed 2-way, 2-position valve to facilitate rapid or feed rate selection. The sharp-edged orifice design minimizes variations in flow due to changes in fluid viscosity, ensuring reliable operation across different working environments. Additionally, the balanced adjustment mechanism allows for easy modifications even at high pressures. The body type of this assembly is a sandwich interface conforming to ISO 08 standards with a stack height of 3.94 inches (100 mm). It is configured for \"Meter out B\" applications and does not include an anodized seal plate. Notably, Sun Hydraulics employs 6061-T651 aluminum for its construction due to its excellent corrosion resistance and strength properties. This material choice supports the manifold's durability without the need for anodizing, which can compromise fatigue life by inducing surface cracks under pressure. The X7HDLANXA is engineered with careful consideration of maximum system pressures and is suitable for systems not exceeding 3000 psi (210 bar) when constructed with aluminum manifolds.

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:

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.
