DLDAZCN224 | 插装阀 » Solenoid Operated » 2-通

此类2位2通电磁阀为直动式，平衡滑阀结构。此阀有常开与常闭两种配置。位置指示开关用来确认阀处在弹簧偏置位置。

线圈必须与此阀一起订购。此阀将在出厂前被设定好，现场不可调。如果是装配需要改变或其它服务，可以将此阀退回到工厂。任何篡改，将违反产品保修条例。
位置指示开关通过CE验证。
当将此阀安装进入它的插孔时，需要使用乌鸦脚扳手或相似的工具，因为位置指示开关使深套筒扳手失去效用。
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。
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。

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.

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.
