The Sun Hydraulics XREALANXD (Material Number: XREALANXD) is a versatile assembly designed to relieve pressure from port 1 to tank port 2 when the pressure at port 1 exceeds a predetermined setting. This unit features a solenoid control that allows the valve to be vented, effectively dropping the pressure to a minimal level. Depending on the configuration, it can be either normally open, maintaining low pressure until the solenoid is energized, or normally closed, maintaining high pressure until activation. It is important to note that this assembly is not suitable for load holding applications due to spool leakage. Additionally, back pressure on tank port 2 directly adds to the valve setting at a 1:1 ratio. The assembly has a capacity of 30 gallons per minute (120 liters per minute) and is designed for line mounting with mounting hole threads of .375-16 UNC-2B inches and a depth of .62 inches. There are eleven mounting holes available for secure installation. The use of corrosion-resistant 6061-T651 aluminum ensures durability and reliability in various environments without anodizing, which could reduce fatigue life by up to 50%. The direct acting nature of this valve makes it ideal for preventing overpressure situations quickly and reliably. It is crucial to consider maximum system pressures when selecting this product, as manifolds made from aluminum are not rated for pressures higher than 3000 psi (210 bar).

Description

This assembly provides 2 functions. It relieves pressure from (port 1) to tank (port 2) when pressure at port 1 exceeds the setting of the valve. The solenoid control allows the valve to be vented, dropping the pressure to a minimal level. This assembly is either normally open meaning the pressure is at a low level until the solenoid is energized or normally closed meaning the pressure is at high level until the solenoid is energized.

Not suitable for use in load holding applications due to spool leakage.
Back pressure on the tank port (port 2) is directly additive to the valve setting at a 1:1 ratio.

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.
