RPES : Pilot-operated, 平衡锥阀  溢流 阀
技术特性 [ + ]

先导控制式,平衡锥阀结构溢流阀为常闭压力调节阀。当进口(口1)压力达到阀设定值,阀开始向油箱(口2)溢流,节流以调节压力。此类阀压力调节精度高、平稳、噪声小、响应速度快并且压力波动随流量变化小。

  • 因为调节发生在阀的内部,所以这些阀不会出现与气蚀相关的问题,即噪音和阀块腐蚀。
  • 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。
  • 此阀对变动的油液温度和油液污染不敏感。
  • 主级的阻尼孔被150微米的不锈钢滤网保护。
  • 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。
  • W和Y控制方式是可以指定或不指定特定设定值。当没有特定值设定要求时,将采用标准设定,并全范围可调。当按特定值设定时,这个特定值将会代表阀的最大设定值。
  • 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.

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.

设置压力的误差在产品的性能参数页中都有详细说明,您可以通过点击可选产品网页中的更多产品信息到达产品性能参数页面。

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.

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.
