DMBFXNN | 插装阀 » Directional » 3-通

这款FLeX系列2位3通电磁阀为直动式，平衡滑阀结构。

此阀可被直接驱动且不需要最小液压操作压力。
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。
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。
线圈插头提供最高IP69K防护等级，详细信息见线圈产品页。
详细产品页面在该网页上部可以下载浏览。
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。
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。

注意：技术参数可能因产品配置而不同。请查看产品配置部分。

Performance Curve for DMBF: FLeX系列 3通, 电磁滑阀换向阀

回到首页

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.

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 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.
