DLDFS : 2通, 软切换, 电磁操作方向 滑阀 阀 (740 Series)
技术特性 [ + ]

This solenoid-operated 2-way, 2-position cartridge is a direct-acting, balanced spool valve with a soft shift feature. The soft shift feature reduces system shock due to valve actuation. The valve is available in either a normally open or normally closed configuration.

This valve is designed to be used with 740 and 747 Series coils.

  • 软切换阀与标准阀可替换,但是流通能力降低。
  • 软切换特性可极大地减少阀驱动时候带来的冲击,但是不宜用在计时很关键的应用中。如果需要精确的斜坡上升或计时控制,请考虑使用Sun的电比例阀。
  • 此软切换特性将比Sun的标准电磁阀显著增加响应时间。响应时间取决于流量,压力,线圈电压,油液粘度和周围的温度。典型响应时间范围为150ms到300ms。
  • 为了获得一致的软切换特性,口1应该有正压力。
  • 电磁套筒组件的疲劳强度至5000 psi(350 bar)。
  • 此阀可被直接驱动且不需要最小液压操作压力。
  • 该类阀的所有配置均配备锌-镍镀层,能够提供1000小时盐雾保护。
  • 线圈插头提供最高IP69K防护等级,详细信息见线圈产品页。
  • 该阀可以使用FLeX高功率或者防爆线圈。
  • 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。
  • 线圈可以双向安装到螺线管上。
  • 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。

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.

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.

  • 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。
