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.

防冲击, 先导式, 平衡锥阀顺序阀带口3外泄

技术特性 [ + ]

先导控制式，防冲击型顺序阀限制最大系统压力，并限制压力上升速度。此类阀的阀口在初始开启之后以恒定速率关小，此速率与设定值及流量无关。调节螺钉决定最大（溢流）设定压力和最小（门限）设定压力。外部泄油口保证阀的设定值与口2压力无关。

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。
当与口3（外泄口）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。
不适合用在顺序油缸应用中。
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）。
口2处的背压对压力设定值没影响。
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。
此阀对变动的油液温度和油液污染不敏感。
不适合使用在负载锁紧应用中。
当进口（口1）压力超过门限设定时，阀打开到油箱（口2）。先导部分以稳定速率向前移动，压缩先导弹簧并增加设定值。当先导部分到达机械限位时，阀达到最大设定值。
主级的阻尼孔被保护以防止污染。
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。

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 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.

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.
