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.

3通, 手动操作, 滑阀换向阀 - 先导流量

流量: .25 gpm1 L/min. | 插孔: T-9A

技术特性 [ + ]

此类先导级2位3通换向阀为手动操作阀且有两种阀芯配置；口1和口2常开或口1和口3常开。此类阀应用在先导级流量场合。手动操作通过SUN的旋转/锁紧手动装置实现且此装置设计适合非经常性手动操作。

此阀为间歇性使用设计，例如手动重载。手动控制安装的预期机械寿命为10,000动作周期。
手动控制安装可以很容易地替代不需要将阀移除阀块或主级元件的场合。
瞬时/扭转控制选项“T”允许操作者通过顺时针扭动旋钮和释放以使阀暂时切换。一旦释放旋钮，阀将返回到其正常位置。
锁定/锁紧控制选项“L”允许操作者通过逆时针扭动旋钮以使阀切换到机械锁定位置。阀会一直保持锁定位置直到操作者顺时针扭动旋钮使阀返回到正常位置。
双操作控制选项“D”不仅允许操作者通过顺时针扭动旋钮以使阀暂时切换，还可以允许操作者通过逆时针扭动旋钮以使阀切换到机械锁定位置。
此阀上的控制须由人手去操作。不可以修改控制，例如紧固手柄上锁紧杆。在任何情况下都不能用其它机械设备去操作控制手柄。
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。
硬化的阀芯和阀套使阀具有一致性操作，低的阀芯泄漏速率和优越的耐磨特性。
利用Sun浮动结构减少由于过量安装扭矩或插孔/插装阀加工误差带来的内部零件粘结的可能性。

常见问题 [ + ]

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.

How big is a drop of hydraulic oil?

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

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.
