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 [ + ]

Les cartouches de distribution normalement ouvertes à action directe, à 2 voies, sont des dispositifs de commutation utilisés dans des circuits au débit modéré. Ils peuvent être utilisés tels quels ou pour activer des distributeurs pilotés ou des cartouches logiques de taille supérieure. La valve commute quand la différence de pression entre les chambres 1 et 4 dépasse le tarage.

L’orifice 3 est utilisable comme orifice de travail.
Le passage de débit entre l’orifice 2 et l’orifice 3 est bidirectionnel.
Ces cartouches, de type à action directe, se caractérisent par des fuites internes faibles et un bas débit de pilotage.
Les distributeurs à action directe et pilotés sont interchangeables. Ils se vissent dans les mêmes cavités et ont les mêmes passages de débit.
Toute pression à l’orifice 4 s’ajoute directement au tarage de la valve.
Cette valve n’est pas bistable, elle est capable de moduler entre les deux positions indiquées sur le schéma.
La pression maximum recommandée à l’orifice 3 est 210 bar. Ceci est dû à la limite de fatigue et non aux limites de fonctionnement hydrauliques.
Cette valve intègre le concept Sun de la cartouche à visser "flottante" qui permet de minimiser les contraintes internes dues à un couple de serrage excessif de la cartouche et/ou à des écarts d’usinage des cavités ou des cartouches.

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

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

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.

Where would I use a DR__ instead of a DP__?

In many circuits the directional cartridge is set to shift at a low pressure no matter how high the pilot pressure goes. If you use a DP__ , the pilot flow increases to significant amounts. A DR__ however will only consume a small amount of flow. A DP__ is useful when you want to block or open the pilot flow to shift the valve.

What parts of the Sun cartridge valve are field serviceable?

Only external seals are serviceable. Sun offers replacement seal kits for all cartridge models. The applicable kit part number can be found in the product page's Technical Data table or by using our Cartridge Seal Kit search function located under Accessories. Please note: Converting the external seals from one material to another does not ensure fluid compatibility with that material due to the existence of internal seals within the cartridge.
