FLeX系列 2通, 直动式, 电磁锥阀换向阀
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。

There are exactly 250 Sun drops in a cubic inch or 15 in a cc.
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.
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.
Yes. All FLeX phase 1 valves are available in the SmartConnect schematic tool, and are also available for submittal to QuickDesign.
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.
Pilot-operated FLeX cartridges shift at rated flow and pressure.
- 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。
