技术特性 [ + ]

此类阀为透气切换，2位3通换向阀且口3与口4常开。当口1透气接油箱，口3和口1的压差超过弹簧力将使阀切换，因此使口3与口2接通。

  • 这个阀并不是双稳态的；其在所示的两个位置之间是可以调节的。
  • 1口泄油流量是起压力补偿功能，其在技术参数里面有相关陈列。
  • 相对于压力1口，必须要有足够的压力在3口，才可以移动阀芯。
  • 这款阀的一项应用就是成对使用，以选择2个马达或泵。
  • 如果一个先导阀用来控制多个该外控分流阀时。油口1处应加入单向阀，从而防止高低压侧之间的相互干扰。
  • 这种泄油动作型是自清洁功能，所以它对污染物不敏感。
  • 更坚硬的阀芯和阀套可以保证一贯的阀芯泄漏等级以及更好的耐磨性能。
  • 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。

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.
