The Sun Hydraulics BBQ (Material Number: BBQ) is a versatile hydraulic sandwich manifold designed with an ISO 05 interface. This model features a unique body type that includes an external port on P, port 3, and maintains a compact stack height of 2.49 inches (63 mm). It is equipped with 11 open cavities, utilizing the T2A cavity style, and supports SAE 6 port sizes. The design choices made in this manifold, such as the use of 6061T651 aluminum, emphasize durability and corrosion resistance without the need for anodizing. The manifold\u2019s configuration allows for easy integration into hydraulic systems that require precise flow control or pressure adjustments within a compact space. Additionally, its design facilitates straightforward assembly into stacks of sandwich valves while ensuring dry sealing surfaces to prevent leakage. This makes it suitable for applications where maintaining a clean and efficient hydraulic system is critical.

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%.
I need a reducer on B. Can I connect the drain to A?	Yes. If you look in the sandwich section you will see that we offer many such packages. When you are pressurizing B, A is connected to tank, allowing the reducer to do its job. When you reverse, the drain or tank port of the reducer is pressurized by A. This increases the setting of the reducer and helps keep the reducer open in the reverse flow direction.
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 profile the ends of your sandwich manifolds? Is there a functional reason?	In the beginning, the bosses (profiles) were cylindrical and centered on the cavity. The boss created a consistant locating spot for the fixture that put in the bolt through holes. The first step in machining sandwiches was to put in the cavities and this was done using big old #4 Warner-Swazey turret lathes. Adding the circular boss was practically free at this point. When 2 or more sandwiches are stacked they look designed rather than a random stack of blocks. This was deemed esthetically pleasing and became a Sun trademark. You can spot Sun sandwiches from across a factory floor. We switched to CNC in the early 80's but kept the circular boss. At this time the first sandwich with 2 cavities on one side was designed, the YFCG XHN AA. Obviously we could not use a circular boss centered on a cavity; we tried a partial circular boss centered on both of the cavities, but the resulting appearance was poor. The solution was a rectangular boss with radiused corners. The resulting profile was pleasing and more modern looking than the circular boss and served a functional purpose--less material had to be removed. We changed all the other sandwich bosses to match. We have applied the boss profile to some custom manifolds.....just because it looks good.
How can I assemble a stack of sandwiches and keep it dry?	Make sure the surfaces are flat and that there are no burrs. Do not polish the surface; machining marks are good. The machining marks help stop the o-rings from acting as pumps. Look for dings on the corners of seal plates that will create gaps. Stud rods or cap screws must not bottom out in the sub-plate. It is very important to assemble a stack of sandwich valves keeping the o-ring sealing surfaces “dry.” The hydrostatic properties of an oil film under the o-rings, and at the seal plate interface, can create a fluid path leading from the pressurized port interfaces to the outside edge of the stack. (Under this condition, as noted in bullet point above, an o-ring can actually act as a “pump.”) So, if you start with a wet seal interface in your stack, there’s a good chance it will always stay wet.
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.
