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.

30%, 蓄能器感应, 泵卸荷阀 - 先导流量

流量: 46 in³/min.0,75 L/min. | 插孔: T-11A

技术特性 [ + ]

蓄能器感应，泵先导卸荷阀用来感应接在阀口1的蓄能器压力。当口1的压力达到阀设定，口2接通口3即溢流阀透气使泵卸荷。此阀在卸荷与复位间有30%的比率；当口1降到阀设定值的70%以下，口2与口3断开即泵将回归给蓄能器充液。此阀需要在口1和泵之间放置一个单独的单向阀。另外一个类型的蓄能器感应，泵卸荷阀QCDC集成了一个单向阀，可适合泵的流量在12gpm (50 L/min)之下。

The pressure differential between unload and reset will be within +2/-3% of the stated ratio of the valve.
蓄能器接入区域是被完全密封的。
由于阀的压差比取决于直径，且阀芯不会被磨损或变形，所以阀的压差比可以保持恒定。
阀芯与阀套之间非常小的间隙，以及先导活塞中良好的密封，最大限度地减少了污染物淤积的可能。
当使用这类阀时，将使用单独的泄油回路，从而防止油路背压所产生不稳定的波动。
注意：需仔细选择调压范围。系统压力的下降以及流量会直接影响到阀的动作。若系统低工作压力同时低压差值，将会使得阀在卸载和重置之间的带宽很窄，系统需精确设计。大流量伴随着大压降，这会抵消阀可操作的压差范围。
Sun具有多款标准的具备多种性能的蓄能器/泵卸载功能元件。这些元件并没有完全在网站上展示，将来我们会逐渐完善网站信息。如果您有迫切地需要，请联系Sun当地的分销商。
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 [ + ]

I need to charge an accumulator. What do I need to know?

See our Highlight on Accumulator Sense, Pump Unload Valves for detailed information.

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.
