技术特性 [ + ]

直动式溢流阀为常闭压力限制阀，常用来保护液压元件，以防止其受瞬态压力的冲击。当压力在进口（口1）达到阀的设定值，阀开始向油箱（口2）溢流，节流以限制压力上升。该阀耐污染，响应迅速，压力超调低，但是牺牲了曲线平滑性。

  • Available in Daman D03 and D05 standard manifolds. Click Here! for more information.
  • 插装阀安装力矩应当为44 lbf ft (60 Nm)以获得最佳性能。
  • 回油箱一侧(2口)背压直接以1:1增加到阀的设定值，该背压应当限制为油箱压力。
  • 不适合使用在负载锁紧应用中。
  • 防调盖里面的调节机构可以被完全拆下来。当阀安装到插孔中后，此状态会将系统油液暴露在空气中。在阀安装好之后调节压力时必须引起注意。调节步骤为：检查设定，卸除压力，进行调节，升压检查新的设定。
  • These valves come with standard settings established at the factory. Any setting adjustments not carried out by the factory should adhere to the valve's setting procedure. We will consider custom settings, set at the factory, on an individual basis. To submit your custom requirements, please use the 'New Product Ideas' link found under the 'Contact' tab.

常见问题 [ + ]
Direct acting, pilot operated, what do I use?

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.

SUN压力控制阀在设置压力时的误差是多少？

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。

Where would I use a kick-down relief?

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.

How big is a drop of hydraulic oil?  

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

Can I use a kick-down relief for my system relief?

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.

What parts of the Sun cartridge valve are field serviceable?
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.
