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.

Bidirectionnel , à action directe limiteur de pression Valve

Caractéristiques techniques [ + ]

The bi-directional, direct-acting relief cartridge is a normally closed, pressure-limiting valve used to protect hydraulic components from pressure transients. When the pressure differential between ports 1 and 2 exceeds the valve setting, the valve starts to open, throttling flow to limit the pressure rise, regardless of the direction.

Capacity from port 1 to port 2 is 25 GPM (95 L/min). Flow from port 2 to port 1 is rated at 10 GPM (40 L/min).
Recommended minimum setting is 1200 psi (85 bar). Note: At settings below 1200 psi (85 bar), the valve is rated for maximum transient flows of 25 GPM (95 L/min) only.
La régulation s’effectuant à l’intérieur de la cartouche, ces valves sont insensibles à la plupart des problèmes associés à la cavitation, c’est-à-dire le bruit et l’érosion du bloc foré.
Les joints de la vis de réglage subissent la pression du système ce qui s’signifie que cette valve ne peut être réglée qu’en l'absence de pression. La procédure de réglage est la suivante : Vérifier le tarage, couper la pression, régler la valve, vérifier à nouveau le tarage...
Cette valve est relativement insensible aux variations de température de l’huile et à la pollution.
Sélectionner une plage de réglage dans laquelle la pression de tarage désirée se situe dans la partie supérieure de la plage afin d'obtenir la meilleure répétabilité de la valve.
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 [ + ]

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

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

Can I use a kick-down relief for my system relief?

Maybe not. We build in a good amount of overlap in the kick-down reliefs to prevent false tripping. This means they are not as fast as our standard pilot operated reliefs. A direct-acting relief valve set just above the kick-down relief valve would be good insurance.

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 kick-down relief?

One graphic example is on a portable grain auger for silos. When the farmer gets caught in the auger the kick-down relief trips and allows him to escape.

Quelles sont les tolérances pour les pressions de tarage des valves de contrôle de pression Sun ?

Pour les pressions de tarage les tolérances sont indiquées dans notre page Performances et Caractéristiques Générales. Un lien vers cette page se trouve également dans l’onglet Ressources Complémentaires de la page produit correspondante.

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.
