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, 气控, 滑阀换向阀- 先导流量

流量: .25 gpm1 L/min. | 插孔: T-8A

技术特性 [ + ]

此类先导级2位2通换向阀为气控，弹簧偏置阀。此类阀有常开与常闭两种配置。此类阀用来作先导级且插孔尺寸为T-8A，所以它常与SUN先导控制的主级阀配合使用。

利用Sun的T-8A 2口插孔可以很好地组合使用Sun主级阀的先导级或外接口控制阀。只需要加工一个插孔来实现控制级和主级功能，从而消除了单独的先导油路。注意：所有2位2通的先导级控制阀使用相同的插孔并在外形尺寸上可互换。故只需要考虑功能上的需求。
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。
此阀的优先油路为从口2到口1。
有不同的先导控制口选项可选。如需详细信息，请参阅选项选择。
硬化的阀芯和阀套使阀具有一致性操作，低的阀芯泄漏速率和优越的耐磨特性。
操作此阀的最小先导压力由以下方程决定：先导压力=20 psi + 压力 @ 口 1 除以100。因此先导压力范围为20到70 psi；公制计算为，先导压力=1,4 bar + 压力 @ 口 1 除以100。因此先导压力范围为1,4到5 bar。
除先导口只能耐压500 psi（35 bar）外，所有口均可耐压5000 psi (350 bar) 。
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 [ + ]

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.
