技术特性 [ + ]

此类2位3通电磁阀为直动式，平衡滑阀结构换向阀。

  • 电磁铁组件的疲劳耐压等级为5000 psi (350 bar)。
  • The R-spool is closed in the transition between its two positions. This results in a higher performance limit at the expense of lower capacity. When used as pilot controls, where capacity is not a factor, the closed transition will provide faster and more consistent response times.
  • 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。
  • 该阀具有手动超越控制选项，详情见“配置”部分。
  • 带D或L控制的型号，手动重载中的止动机构是用来作临时驱动用途。
  • 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。
  • 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.

备注 [ + ]
  • 当选择Sun阀块时，请检查插装阀的间隙要求。不同的阀控制方式以及线圈要求的间隙不一样。
  • 在阀的最大尺寸之外需增加额外的2.00 inches (50,8 mm)，以进行线圈的安装和移除。
