2通, 电磁滑阀换向阀 - 先导流量

流量: .25 gpm1 L/min. | 插孔: T-8A
DAAA : 2通, 电磁滑阀换向阀 - 先导流量
技术特性 [ + ]

此类2位2通电磁阀为直动式,平衡滑阀结构先导级阀且常用来作其他大流量阀的先导级。此阀有常开与常闭两种配置。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。

  • 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。
  • 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。
  • 因高效率的套筒设计,只需要12 瓦特来切换阀。
  • 阀表现出极低的泄漏速率;小于10滴/分钟。@5000 psi(0,7 cc/min @ 350 bar)。
  • 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。
  • 手动推式紧急操作是一个标准特性。
  • 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。
  • 线圈可以和Sun的系列P先导级电磁阀产品互换并可从另外一个方向上安装在套筒上。
  • 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.

  • 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。
