技术特性 [ + ]

相位单向阀是由一对背靠背单向阀组成并在口1配置由机械驱动的阀芯。此阀常安装在液压缸活塞。当液压缸到达行程终点,相位单向阀的阀芯会被推离阀座从而使液流通过活塞。此阀可以使两个液压缸达到同一个相位。

  • 这种阀并不能承受侧向压力。驱动力方向必须是轴向的,作用力方向和阀轴的方向应该在5°以内。
  • 这种阀并不意味着可以采用凸轮驱动。
  • 这种阀并不能用于代替机械制动。
  • 除阀本身之外,阀芯至停止位的最大冲击距离必须小于0.047in(1.2mm)。
  • 注意:T-162A孔型的2口结构并不适用该类阀。
  • 单向阀具备非常低的泄漏等级,其中最大泄漏量每分钟少于1滴(0.07cc/min。)
  • 当液压缸伸出时,很有可能带着重大负载冲击端盖。这种安装在活塞中的相位控制单向阀就可以降低不必要的冲击力。
  • 如果你想知道液压缸内部各处的压力,这种相位控制阀可以很好地避免由于压力保持阀而产生的内部被困压力。
  • 用在垂直液压缸中的相位单向阀可以在动作末端排出内部的空气。
  • 相位单向阀使用于主从动液压缸中,可以简单地利用机械结构控制两缸在双向的同步。他可以很好地应用于双缸的动作控制。
  • 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

Because of the very high ratio, the COFO has limited capacity. The discharge path is across a .050 inch (1,3 mm) diameter orifice. If you have large accumulators combined with low precharge pressures, this may not discharge the energy quickly enough. Using the COFO XDN cartridge in conjunction with an LODA XDN will provide capacity for larger applications.

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.
