技术特性 [ + ]
高压侧梭阀经常应用在全时差动回路中。当两个工作口(口2和口4)的压力相等,此阀在弹簧对中作用下处于所有油口都堵住的中位。当两个工作口(口2和口4)中的任何一个口处于较高压力,此口便会与公共口接通(口3)。
- 这款阀可以对再生回路中活塞伸出情况下的负载进行超驰控制。但由于存在阀芯泄漏,它不能防止微动。
- 高硬度的阀芯/阀套结构可以提供很好的耐磨性以及减少相互泄漏。
- 虽然这种阀采用的是4口的插装孔,但是鼻尖口(1口)是不使用的。
- Sun浮动式的结构可以最大限度地减少由于过大的安装扭矩以及孔型加工的误差所造成的干涉现象。

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