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.

Caractéristiques techniques [ + ]

Cet ensemble consiste en une cartouche limiteur de pression à action directe, qui est une valve normalement fermée utilisée pour protéger les composants hydrauliques des pics de pression. Quand la pression en entrée (orifice 1) atteint la valeur de tarage, la valve commence à s'ouvrir vers le réservoir (orifice2) en étranglant le débit dérivé pour limiter l’augmentation de pression dans le circuit. Ces valves sont silencieuses, sans à-coups, et étanches, peu sensibles à la pollution, non sujette à la sédimentation, et ont un temps de réponse très rapide. L'électrovalve 2 voies /2 positions by-pass le limiteur de pression, permettant ainsi de décharger le système.

Now available with FLeX Series solenoid valves. See CONFIGURATION section, SOLENOID DESIGNATION to specify.
Toute contre-pression à l’orifice 2 (retour au réservoir) augmente directement la valeur de tarage de la valve dans un rapport de 1/1.
Cette valve convient aux applications de maintien de charge.
Cet ensemble assure la protection des pompes est des moteurs contre les pics de pression dus aux variations brusques de charges, en particulier avec les pompes à cylindrée variable dont le mécanisme de changement de cylindrée est parfois trop lent pour absorber les pics de pression.
Cet ensemble limiteur de pression à action directe a un temps de réponse rapide qui permet de réduire les pics de pression, et un faible débit de fuite lors de la fermeture (moins de 5 gouttes/min [0,3 cm3/min] à 85% de la pression d'ouverture).
The seals on the adjust screw are exposed to system pressure which means this valve can only be adjusted when the pressure is removed. The setting procedure is; check the setting, remove the pressure, adjust the valve, check the new setting.

Quel est le volume d'une goutte d'huile hydraulique ?

Il y a exactement 15 gouttes Sun dans un centimètre cube.

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, 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.

Notes [ + ]

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.
