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 [ + ]

此手动操纵，2位3通方向阀为直动式，锥阀结构可用来控制液压油路中的液流方向。此类阀为口1到口2常开，口3关闭。操作此阀将使口2到口3打开，口1关闭。所有的流道为双向可流通且关闭的流道为双向关闭。由于锥阀结构，此阀泄漏量极低。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。

这款阀适用于间歇性动作的场合，如同人工紧急操作那样。这种人工控制的装置机械预期寿命大致在7000个周期。
这种瞬间/旋转式的控制方式“T”将可以使操作器瞬间顺时针转动扳手，释放作用力。一旦释放，阀将会回到正常的位置。
这种制动/定位控制方式“L”将可以通过操作器逆时针旋转固定），从而移动阀芯使其固定于机械制动位置。当操作器瞬时针转回，阀芯回位。请注意，该制动位置只是针对于一些特殊应急状况，并不适用于负载保持的应用。
这种双作用控制形式“D”允许操作杆顺时针旋转起回位功能，逆时针机械定位功能。请注意，该制动位置只是针对于一些特殊应急状况，并不适用于负载保持的应用。
这里阀的控制形式都是需要操作者用手调节。这里的控制不因被改装，例如安装一个操作杆在已有操作器上。在任何情况下，操作器都不应被其他装置使用。
此阀将会有非常少的泄漏量；在5000psi情况下，少于10滴/分（0,7 cc/min @350bar）
此阀适合在口3进行负载锁紧应用。手动重载中的止动机构是用来作临时驱动用途。
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 [ + ]

How big is a drop of hydraulic oil?

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

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.

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.
