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.

2通, 先导式, 换向阀带内泄到口3 - 常开

流量: 7 gpm28 L/min. | 插孔: T-11A

技术特性 [ + ]

常开，先导控制，2通换向阀为切换装置，常用在中等流量油路中。它们可以单独使用或者用来驱动更大流量的先导控制换向阀或者逻辑阀。当口1与口3之间的压差超出设定时，此阀将切换。

3口的压力直接叠加到阀的设定值上。鉴于如此，3口不可以最为工作油口使用。如需使用3口，请考虑4口的插装阀。
直动式和先导式的插装阀是可以相互替换的。他们复合相同的孔型，以及相同的流道。
这个阀并不是双稳态的；其在所示的两个位置之间是可以调节的。
3口的最大压力需要限制在3000psi（210bar）。这是基于疲劳强度的要求而非工作运行的要求。
当先导压力超过阀的设定值时，先导流量就需要考虑。请参考阀压力值设定以上时，阀的先导泄流性能和负载压力曲线。如果这是个需要注意的问题，制动式应该是更好的选择。
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.

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.

I used a DP** in a circuit but it hangs. What happened?

DP**s and DR**s are from the reducer/reliever family and are very capable of modulating. They are not bistable.

Where would I use a DR__ instead of a DP__?
