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.

技术特性 [ + ]

这款2位2通电磁阀为直动式，平衡滑阀结构，带有软切换功能。软切换功能能有效降低阀动作时带来的系统冲击。有常开或者常关配置选项。该阀适用于740和747系列线圈。

软切换阀与标准阀可替换，但是流通能力降低。
软切换特性可极大地减少阀驱动时候带来的冲击，但是不宜用在计时很关键的应用中。如果需要精确的斜坡上升或计时控制，请考虑使用Sun的电比例阀。
此软切换特性将比Sun的标准电磁阀显著增加响应时间。响应时间取决于流量，压力，线圈电压，油液粘度和周围的温度。典型响应时间范围为150ms到300ms。
为了获得一致的软切换特性，口1应该有正压力。
电磁铁组件的疲劳耐压等级为5000 psi (350 bar)。
此阀可被直接驱动且不需要最小液压操作压力。
该类阀的所有配置均配备锌-镍镀层，能够提供1000小时盐雾保护。
线圈插头提供最高IP69K防护等级，详细信息见线圈产品页。
该阀可以使用FLeX高功率或者防爆线圈。
此阀采用湿式衔铁线圈设计。这意味着衔铁周围的工作流体介质将曝露在线圈所产生热场中。如果线圈长时间通电，这将是一个影响因素。一些液体，特别是水/乙二醇混合物，会在长时间高温下分解并形成凡立水，而这将会影响阀的功能。
不同的线圈接头与电压选项都是可选的，也同时可选带或不带浪涌保护。
线圈的独特电磁设计使电磁阀有更高的效率，单位瓦特产生高的阀芯驱动力，从而使阀有可靠的切换。
线圈可以双向安装到螺线管上。
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.
