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.

先导式, 平衡锥阀顺序主级带集成T-8A控制插孔

流量: 30 gpm120 L/min. | 插孔: T-2A

技术特性 [ + ]

此类阀为带集成先导级控制插孔的常闭调节元件。它带外泄口并为平衡锥阀结构设计。先导级控制插孔可接受任何T-8A插孔的压力控制插装阀。当进口（口1）压力达到先导级控制阀的设定，阀开始接通口2，节流以调节压力。先导级控制阀的设定决定了进口（口1）与外泄口（口3）之间的压力降。在口2背压升至设定值之前，此类阀对此不敏感。如果回路中有压力存在，它们可以用来代替2口溢流阀完成对压力的调节。

所有3口顺序阀在尺寸和功能上可互换（如：给定的外形结构尺寸阀拥有相同的流道，相同的插孔）。
当与口3（外泄）压力相关的口1（进口）压力超过阀的设定值而升高时，先导流量随之增加。
主级的阻尼孔被150微米的不锈钢滤网保护。
口3处的压力直接以1:1的比例增加到阀的设定值上，口3处的压力不能超出5000 psi（350 bar）。
注意：带-8控制选项，应首先用正确的扭矩安装主级阀。然后用合适的扭矩将T-8A先导级控制阀安装进主级阀中。
-8控制类型允许通过T-8A插孔将先导级控制阀直接旋进溢流阀的顶部。这些先导级控制阀需单独采购并包括电比例，电磁，气控先导，液控先导操作。请参照先导级控制阀。
因为调节发生在阀的内部，所以这些阀不会出现与气蚀相关的问题，即噪音和阀块腐蚀。
可在口2接受最大压力；适合应用在交叉端口的溢流油路中。
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 [ + ]

What does Sun mean by the term sequencing?

A sequence valve opens when the pressure at port 1 exceeds the setting of the valve. When pressures at port 1 and port 2 both exceed the setting of the valve the valve goes full open, or sequences. When this happens flow can go in either direction, just so long as port 1 stays above the setting.

SUN压力控制阀在设置压力时的误差是多少？

设置压力的误差在产品的性能参数页中都有详细说明，您可以通过点击可选产品网页中的更多产品信息到达产品性能参数页面。

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.
