技术特性 [ + ]
此直动式,3位4通滑阀结构电磁阀为弹簧对中到中位机能。当线圈A得电,流道为口3(P)到口2(A)和口4(B)到口1(T)。当线圈B得电,流道为口3到口4和口2到口1。
- 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。
- 在差动油路中,较高的回油流量应直接从口2(A)流向口1(T)。
- 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。
- 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。
- 线圈可以和Sun的系列1电磁阀产品互换并可从另外一个方向上安装在套筒上。
- 线圈接头等级可提供至IP69K。请见单个线圈产品的详细产品说明。额外的风雨线圈和工具包可提供更完善的环境防护。
- 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.
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.

- 此装配体中的2个线圈可以互换,但一旦装配接线完成,与阀体六面体相近的为线圈A,与线圈螺母相近的为线圈B。
