技术特性 [ + ]


  • 所有2口溢流阀(除了先导溢流阀)在尺寸和功能上可互换(如:给定的外形结构尺寸阀拥有相同的流道,相同的插孔)。
  • 可在口2接受最大压力;适合应用在交叉端口的溢流油路中。如果应用在交叉端口的溢流油路中,请考虑滑阀泄漏。
  • 所有弹簧范围的最小设定为75 psi (5 bar)。
  • 因为滑阀的泄漏,不适合使用在负载锁紧应用中。
  • 油箱口(口2)处的背压直接以1:1的比例增加到阀的设定值上。
  • 主级的阻尼孔被保护以防止污染。
  • 配置EPDM密封圈的插装阀可用在磷酸酯液压油系统。暴露在石油基液压油或润滑油脂中会损坏密封圈。
  • 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。

Maybe not. We build in a good amount of overlap in the kick-down reliefs to prevent false tripping. This means they are not as fast as our standard pilot operated reliefs. A direct-acting relief valve set just above the kick-down relief valve would be good insurance.

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.


One graphic example is on a portable grain auger for silos. When the farmer gets caught in the auger the kick-down relief trips and allows him to escape.

There are exactly 250 Sun drops in a cubic inch or 15 in a cc.

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.
