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, 外接口操作, 换向阀带内泄到口3 和集成T-8A控制插孔 (口1到口2打开, 口3关闭)

流量: 15 gpm60 L/min. | 插孔: T-2A

全部展开

技术特性 [ + ]

此类阀为3通换向阀（口1到口2打开，口3关闭）并带一个集成先导级控制插孔。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。当有流量流过安装在T-8A插孔中的先导级控制阀时，此阀将切换。

注意：先导级应该按照正确的扭矩安装后，之后再将T-8A的先导控制部分按照要求的扭矩旋入。
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。
在1口和2口之间的液流是双向的。
3口的压力将会阻止阀口的打开。因为如此，3口不能连接工作口。如果这种情况发生，推荐使用4口的结构。
相对于3口，1口必须有足够大的压力才可以操作阀动作。
这种-8控制结构允许先导控制阀直接通过T-8A的孔型安装进入换向阀的底部。这种先导控制阀将被单独出售，其中包括电磁先导动作，气体先导动作以及液压先导动作。具体请查阅先导控制阀。
技术指标中泄漏值时针对每一路的值。
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.
