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.

低压侧, 3位, 热油梭阀带延时切换

技术特性 [ + ]

低压侧（热油）梭阀可以将闭式油路系统中低压侧的热油疏散出去。当两个工作口（口2和口4）的压力相等，此阀在弹簧对中作用下处于所有油口都堵住的中位。当两个工作口（口2和口4）中的任何一个口处于较高压力，另一个口便会与公共口接通（口3）。延迟切换梭阀可防止热油油路下段流量瞬变。

这种阀将会迅速回至中位以及停留在中位，直至如下2种情况的产生。
这种阀可以防止热油的瞬间泄流。此梭阀阀芯一直位于中位直到一方的的压力降低。一旦一方的压力下降，阀芯将会以控制方式保持2s时间慢慢动作。
只要2口和4口的压力保持在300psi（20bar）和热油溢流压力之和或者比其大情况，这种阀都将会位于中位。例如：当设定热油溢流压力为200psi（14bar）的时候，此梭阀开启的条件是有一边的压力降至低于500psi（34bar）的情况。
阀芯采用了液压制，可消除机械冲击防止潜在的内部损坏。
液压制动需要从高压侧油口（2口或4口），提供小量的油液流向公共口3。
由于是液压制动，所以它的另一个特性是，热油溢流压力设定需要在中位状态下进行。
虽然这种阀采用的是4口的插装孔，但是鼻尖口（1口）是不使用的。
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 [ + ]

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.

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.
