DFCB8 : 2通, 锥阀方向阀 带集成T-8A控制插孔 - 控制 2-1
技术特性 [ + ]

此类阀为2位2通锥阀结构且集成了一个先导级控制插孔。它控制口2到口1的液流,具有极低的泄漏率并且两个油口都可承受5000psi(350 bar)压力。安装进T-8A插孔中的先导级电磁阀和此阀组成大流量换向阀。其他可选择的先导级有手动,液压和气动先导级阀。

  • 注意:先导级应该按照正确的扭矩安装后,之后再将T-8A的先导控制部分按照要求的扭矩旋入。
  • 这种-8控制结构允许先导控制阀直接通过T-8A的孔型安装进入换向阀的底部。这种先导控制阀将被单独出售,其中包括电磁先导动作,气体先导动作以及液压先导动作。具体请查阅先导控制阀。
  • 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。
  • 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.

In many circuits the directional cartridge is set to shift at a low pressure no matter how high the pilot pressure goes. If you use a DP__ , the pilot flow increases to significant amounts. A DR__ however will only consume a small amount of flow. A DP__ is useful when you want to block or open the pilot flow to shift the valve.

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.
