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.

技术特性 [ + ]

流量保险阀用来使液压驱动器在液压管路破裂的情况下保持位置。此阀可以让油液流出或流入驱动器，但是如果流出驱动器的流量超出此阀的设定值，此阀会迅速关闭。注意：因为此阀响应迅速，此阀对超出设定值的任何瞬态流量都很敏感。

客户必须设定流量等级。工厂设定流量精度为用户要求的±15%。
配置EPDM密封圈的插装阀可用在磷酸酯液压油系统。暴露在石油基液压油或润滑油脂中会损坏密封圈。
当1口流向2口的流量大于阀的设定值时，阀将会关闭。自会有当1,2口的压力相等时，阀才可以再次重置。
流量设定必须比系统最大流量还要大25%。用户必须在订货时提供设定流量值。
这种滑阀式结构使得泄漏存在。所以执行器的微动将可能存在。
Sun浮动式的结构可以最大限度地减少由于过大的安装扭矩以及孔型加工的误差所造成的干涉现象。

常见问题 [ + ]

Can I use a flow fuse to prevent the loss of oil?

NO! Flow fuses are meant to prevent the uncontrolled movement of an actuator in case of hose failure.

Can I use a flow fuse to provide fire protection?

NO! Flow fuses are meant to prevent the uncontrolled movement of an actuator in case of hose failure. To avoid false tripping they must be set above the typical system flow, usually 50% above. On a 4 gpm (15 L/min.) circuit the flow fuse may need to be set at 6 gpm (23 L/min.) to avoid false tripping. Hoses do not normally fail totally, they spring a leak. If the hose springs a 5.5 gpm (21 L/min.) leak the flow fuse will not trip. 5.5 gpm (21 L/min.) of hydraulic fluid will feed a fire that would heat a small town in Ohio (Denmark) in January!

How should I choose the setting of a flow fuse?

It is very, very difficult to predict the transient flows in a system. We say at least 25% above maximum normal system flow and should say 50%. Don’t back yourself into a corner by sizing a flow fuse at the top end of its range unless you can test it. If you have an FQCA in a 4 gpm (15 L/min.) circuit, set at 6 gpm (23 L/min.) and it false trips, you are out of luck. Select an FQEA and leave yourself some room for tuning.

Every time I try to lower my load the flow fuse trips. What's wrong?

What's wrong is that every time you start to lower your load, you get a flow transient that exceeds the setting of the flow fuse and trips it. Sun's flow fuses are very consistent and very fast.

How big is a drop of hydraulic oil?

There are exactly 250 Sun drops in a cubic inch or 15 in a cc.

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.
