技术特性 [ + ]

2位,定位,4通换向阀为6油口阀,它可以配置成其它不同的3种阀芯类型。口3为供油口且各油口都可承受5000psi(350 bar)压力。此先导换向阀的流通能力取决于指定的阀芯类型.

  • 所有的口都可承受5000psi(350bar)压力,包括想x,y先导口(5口和6口)。
  • 技术指标中泄漏值时针对每一路的值。
  • 先导口5,6是与工作口之间完全密封。
  • 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。

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.
