DTAF : FLeX系列 2通, 直动式, 电磁锥阀换向阀
技术特性 [ + ]

此类FLeX系列电磁阀为2位2通，直动式，锥阀结构。该阀提供常开和常闭两种配置，采用液压平衡设计，具有极低泄漏，控制液流的双向通断。此阀可以直接安装进SUN的先导控制或外接口控制阀的插孔中，用来提供集成先导控制。

  • 此阀可被直接安装进Sun先导控制和外接口控制阀中以提供电磁先导控制功能。单独的先导油路被去除，只需要加工一个插孔来整合先导控制级和主级的功能。
  • 适合负载锁紧回路。
  • 配置EPDM密封圈的插装阀可用在磷酸酯液压油系统。暴露在石油基液压油或润滑油脂中会损坏密封圈。
  • 设计以及测试通过1000万次开关工作循环。
  • 疲劳以及爆破压力等级符合新的NFPA测试标准T2.6.1 R2014。
  • 相近的尺寸下拥有比竞争对手更高的通流能力。
  • 使用CFD流体仿真软件进行几何形状优化设计。
  • 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。
  • 常闭式选项可以使用FLeX低功率，高功率或者防爆线圈。常开式选项仅可以使用FLeX高功率或者防爆线圈。
  • 线圈插头提供最高IP69K防护等级，详细信息见线圈产品页。
  • 该阀提供推式手动应急选项。
  • 该阀具有极低的泄漏量 - 0.004 in³ (0.07 cc³)/min (1 滴/min)。
  • 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。
  • 详细产品页面在该网页上部可以下载浏览。
  • 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。
  • 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.

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.
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.

Is the FLeX program available in QuickDesign SmartConnect?

Yes. All FLeX phase 1 valves are available in the SmartConnect schematic tool, and are also available for submittal to QuickDesign.

Do FLeX valves utilize a floating nose design?
Yes. All FLeX valves utilize the Sun floating nose design.
What is the difference between nominal and maximum flow capacity?
Nominal flow capacity is based on performance limits. Maximum flow capacity is based on pressure drop. When selecting any direct-acting solenoid valve, first check the performance limits plot, then check if pressure drop is acceptable.
What is the flow performance limit of pilot-operated FLeX cartridges?

Pilot-operated FLeX cartridges shift at rated flow and pressure.

Why is the minimum opening pressure (bias spring pressure) on pilot-operated FLeX cartridges lower than competitor product?

FLeX pilot-operated cartridges do not have a bias spring in their open state. These valves will shift with less than 5 psi differential. This results in pilot-operated shift performance with direct-acting minimum pressure operation.

备注 [ + ]
  • 对于采用O控制（旋钮调节，带面板锁）的系列1插装阀，面板上需要留一个直径0.75 in. (19 mm)的孔。
  • 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。
