技术特性 [ + ]

该FLeX系列电磁操作式2级溢流阀用于调节压力。该阀不通电时先导油路被阻断,阀阻止油液从口1流向口2,此时相当于关闭的滑阀式换向阀。通电时为溢流阀状态,该状态下口2接油箱,当口1的压力到达溢流设定值时,阀口自动节流以维持压力。设定压力可以通过调节螺钉进行调节。

  • 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。
  • 设计以及测试通过1000万次开关工作循环。
  • 疲劳以及爆破压力等级符合新的NFPA测试标准T2.6.1 R2014。
  • 相近的尺寸下拥有比竞争对手更高的通流能力。
  • 该类阀的所有配置均配备锌-镍镀层,能够提供1000小时盐雾保护。
  • 线圈插头提供最高IP69K防护等级,详细信息见线圈产品页。
  • 该阀可以使用FLeX高功率或者防爆线圈。
  • 2口处的背压将会以1:1直接增加到设定值上。
  • 主级阻尼由150微米不锈钢滤网提供保护。
  • 2口承受最高压力。
  • 该阀的所有配置包含一个不可移除的调节螺钉。
  • FLeX系列电磁溢流阀与Sun出品XMD可扩展放大器完美匹配。
  • 详细产品页面在该网页上部可以下载浏览。
  • 不同的线圈接头与电压选项都是可选的,也同时可选带或不带浪涌保护。
  • 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.

Yes. All FLeX phase 1 valves are available in the SmartConnect schematic tool, and are also available for submittal to QuickDesign.

Yes. All FLeX valves utilize the Sun floating nose design.
Nominal flow capacity is based on performance limits. Maximum flow capacity is based on pressure drop. When selecting any direct-acting solenoid valve, first check the performance limits plot, then check if pressure drop is acceptable.
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.
