DBAP : 3通, 气控操作式, 滑阀换向阀 - 先导流量
技术特性 [ + ]

此类先导级2位3通换向阀为气控,弹簧偏置阀且有两种阀芯配置;口1和口2常开或口1和口3常开。

  • 有不同的先导控制口选项可选。如需详细信息,请参阅选项选择。
  • 硬化的阀芯和阀套使阀具有一致性操作,低的阀芯泄漏速率和优越的耐磨特性。
  • 操作此阀的最小先导压力由以下方程决定:先导压力=20 psi + 压力 @ 口 1 除以100。因此先导压力范围为20到70 psi;公制计算为,先导压力=1,4 bar + 压力 @ 口 1 除以100。因此先导压力范围为1,4到5 bar。
  • 除先导口只能耐压500 psi(35 bar)外,所有口均可耐压5000 psi (350 bar) 。
  • 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.

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.
