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 [ + ]

Ce clapet anti-retour qui se ferme quand on le pilote a un rapport de pilotage de 120/1. Il est destinée spécifiquement à décharger un accumulateur au moment de l’arrêt de la pompe. En absence de pression en sortie de pompe (chambre 3) la valve est passante entre l’accumulateur (chambre 1) et le réservoir (chambre 2). 3,5 bar (50 psi) sur la chambre 3 ferment la valve pour une pression d’accumulateur jusqu’à 420 bar (6000 psi), Quand la pression de pompe est inférieure à 20 bar (300 psi) un débit de fuite est créé entre la chambre 3 et le réservoir (chambre 2) pour assurer la décharge de l’accumulateur quand la pompe s’arrête. Quand la pression dépasse 30 bar (300 psi) la fuite est stoppée pour un meilleur rendement.

Cette valve comporte un siège en acier traité qui a d’excellentes caractéristiques contre l’usure et qui est peu sensible à la pollution.
Note : L’accumulateur se décharge au travers d’un gicleur de diamètre 1,27 mm. Le temps de décharge de grands accumulateurs avec une pression de gonflage basse peut être trop long. Dans ce cas, des circuits de 2 valves augmentent considérablement la capacité. Voir les conseils techniques (FAQ).
Cette valve de conception à clapet a un débit de fuite très faible en provenance de l’accumulateur.
Le débit de fuite de la ligne du signal de la pompe n’intervient que lorsque la pompe est mise à vide à une pression inférieure à 20 bar.
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.

FAQs [ + ]

I need to discharge a large accumulator. How can I increase the capacity of my discharge circuit?

Because of the very high ratio, the COFO has limited capacity. The discharge path is across a .050 inch (1,3 mm) diameter orifice. If you have large accumulators combined with low precharge pressures, this may not discharge the energy quickly enough. Using the COFO XDN cartridge in conjunction with an LODA XDN will provide capacity for larger applications.

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

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.
