技术特性 [ + ]

This solenoid-operated 2-way, 2-position cartridge is a direct-acting, poppet-style directional valve. The valve is only available in a normally closed configuration. Due to the poppet style construction, this valve has extremely low leakage.

Many poppet style directional valves pass a small amount of fluid when the pressure across them changes suddenly. This is due to the compressibility of the fluid. This valve has been designed to prevent this from happening.

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

  • 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。
  • 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)。
  • 线圈插头提供最高IP69K防护等级,详细信息见线圈产品页。
  • 该阀具有手动超越控制选项,详情见“配置”部分。
  • 提供了一个组合的阀座/阀芯设计以提高密封完整性。
  • 此阀适合负载锁紧应用。在动力源失效的情况下,阀会在弹簧偏置下关闭。
  • 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.

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。
