技术特性 [ + ]

此类2位2通电磁阀为先导控制式，锥阀结构且带反向自由流单向阀。此阀有常开与常闭两种配置。此阀为锥阀芯结构，因此具有极低的泄漏。

电磁铁组件的疲劳耐压等级为5000 psi (350 bar)。
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。
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）。
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。
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。
Sun浮动式的结构可以最大限度地减少由于过大的安装扭矩以及孔型加工的误差所造成的干涉现象。

常见问题 [ + ]

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.

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.

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.
