Assembly Build Process

Sun's Assembly Build Process allows you to configure a cartridge and manifold, or main stage and pilot stage cartridge, and build a digital assembly in three dimensional space. The resulting output of this process is the assembly product page, including configuration-specific images, symbols, product information and CAD files for download.

The Assembly Build Process can be accessed from either a cartridge or manifold product page. Only valid choices are allowed.

From a manifold page, you must first choose your cartridge function. Once you choose your function, click on the BUILD ASSEMBLY button below the WHERE TO BUY BUTTON. Once clicked, you will be presented with valid cartridges for your manifold. Select the cartridge of your choice and follow the instructions at the top of the page. If your particular combination has been generated before, the resulting assembly page will be available immediately. If not, you will be asked to enter your email address. Once the page is complete, an email will be sent to you including a link to the assembly product page.

From a cartridge product page, click on BUILD ASSEMBLY and you will be presented with a listing of compatible manifolds. In the case of main stage and pilot stage cartridges, you can either build a cartridge to cartridge assembly or a cartridge to manifold assembly. Once your choice has been made, follow the instructions at the top of the page. If your particular combination has been generated before, the resulting assembly page will be available immediately. If not, you will be asked to enter your email address. Once the page is complete, an email will be sent to you including a link to the assembly product page.

Please note that the Assembly Build Process is an automated process. It can be utilized at any time. Pages are generated typically within minutes but delays can occasionally be expected. In the event of a delay, a team at Sun will work to resolve the issue to ensure you receive your information as quickly as possible.

Restrictive Balance de pression assemblage

Function

Restrictive pressure compensator

Développer

Caractéristiques techniques [ + ]

Ce bloc comporte un compensateur normalement ouvert de type 2 voies fonctionnant sur l’orifice P, et un sélecteur de circuit choisissant la plus haute pression entre les orifices A et B. Sa fonction est de maintenir une perte de charge relativement constante au travers du distributeur, isolant ainsi le tiroir des importantes forces parasites dues au flux. Ceci est réalisé en étranglant l’alimentation sur P. La perte de charge constante crée une régulation du débit compensée en pression en sortie du distributeur.

Ce bloc est destiné à être utilisé dans un système load sensing multi-tranches ou avec une pompe load sensing.
La pression différentielle au travers de l’étranglement (distributeur) varie selon le débit et la pression du système. Elle est au plus haut quand le débit est nul, et chute quand le débit augmente.
Cette valve est également appelée hydrostat.

FAQs [ + ]

Direct acting, 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.

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%.

Pour cet ensemble il n'y a pas besoin de plaque porte-joints.
For detailed information regarding the cartridges contained in this assembly, click on the models codes shown in the Included Components tab.
Important: La pression maximum du système doit être considérée avec une grande attention. La limite de pression maximum à laquelle le bloc peut être utilisé dépend de la matière du bloc, alors que le type et la dimension des orifices sont secondaires. Les blocs forés fabriqués en aluminium ne sont pas prévus pour des pressions supérieures à 210 bar (3000 psi), et ce quelles que soient les types et dimensions des orifices spécifiés.
