2通, 电磁锥阀换向阀 - 在单向阀后

流量: 10 gpm40 L/min. | 插孔: T-11A
HDDA : 2通, 电磁锥阀换向阀 - 在单向阀后
技术特性 [ + ]

此类在单向阀后的电磁阀为一个组合阀。它利用直动式,锥阀结构电磁阀置于单向阀后面组合成一个三通路。单向阀的自由流方向为从进口(口2)到系统口(口1)。当电磁阀失电,口2到口3是不通的。此种组合阀常用于升/降应用中并可直接集成到驱动器上。

  • 电磁铁组件的疲劳耐压等级为5000 psi (350 bar)。
  • 适合负载锁紧回路。
  • 此阀有几种不同的手动紧急操作选项,包括无手动紧急操作。见以下可选选项。请注意:风雨线圈不兼容手动紧急操作功能。
  • 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。

常见问题 [ + ]

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.

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。
