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.

Tiroir d'échange, à action directe, 3 positions, côté basse pression

Capacité: 15 gpm60 L/min. | Cavité: T-31A

Caractéristiques techniques [ + ]

Les sélecteurs avec pilotage par la basse pression, permettent aux circuits hydrostatiques de se délester en huile chaude. Quand les 2 lignes du circuit (chambres 2 et 4) sont à la même pression, la valve est centrée par des ressorts dans une position où tous les orifices sont fermés. Quand l’une des lignes (chambre 2 ou 4) voit une pression plus élevée, la ligne opposée est connectée à l’orifice de délestage (chambre 3)

Note : Une faible pression de commutation peut aboutir à ce que la pression de gavage seule suffise à commuter le tiroir de façon aléatoire. Il faut en tenir compte lors du choix de la pression de commutation.
Bien que cette valve aille dans une cavité à 4 orifices, le nez de la cartouche (orifice 1) n’est pas utilisé.
Cette valve n’est pas équipée de butée hydraulique et donc n’a pas de débit de pilotage. Certains circuits, autres que les transmissions hydrostatiques ne tolèrent pas de fuites supplémentaires.
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.

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.
