双向, 直动式 溢流阀 - 先导流量

流量: .25 gpm1 L/min. | 插孔: T-11A
RBAD : 双向, 直动式 溢流阀 - 先导流量
技术特性 [ + ]

直动式,先导级溢流阀结合了背靠背的单向阀。此阀常用于2个先导控制式阀的远程压力控制或驱动器的两端热溢流。由于此类阀流量能力仅限于先导级别,因此它们应该与其它需相匹配先导流量要求的阀一起使用。

  • 背靠背的单向阀可防止两个正在远程控制阀之间发生串扰。
  • 一个调节可以控制两个阀。
  • 单向开启压力为15 psi (1 bar)。
  • 口3处的压力直接加到阀的设定上。
  • 适合负载锁紧应用。
  • 热溢流表明此阀可以防止流体热膨胀引起的过压。
  • 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.

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.

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.

  • 对于采用O控制(旋钮调节,带面板锁)的系列1插装阀,面板上需要留一个直径0.75 in. (19 mm)的孔。
