技术特性 [ + ]

此手动操纵,2位2通方向阀为直动式,平衡滑阀结构可用来控制液压油路中的液流方向。此类阀有常开或常闭配置。手动操作通过SUN的旋转/锁紧手动装置实现且此装置设计适合非经常性手动操作。

  • 这款阀适用于间歇性动作的场合,如同人工紧急操作那样。这种人工控制的装置机械预期寿命大致在7000个周期。
  • 这种瞬间/旋转式的控制方式“T”将可以使操作器瞬间顺时针转动扳手,释放作用力。一旦释放,阀将会回到正常的位置。
  • 这种制动/定位控制方式“L”将可以通过操作器逆时针旋转固定),从而移动阀芯使其固定于机械制动位置。当操作器瞬时针转回,阀芯回位。请注意,该制动位置只是针对于一些特殊应急状况,并不适用于负载保持的应用。
  • 这种双作用控制形式“D”允许操作杆顺时针旋转起回位功能,逆时针机械定位功能。请注意,该制动位置只是针对于一些特殊应急状况,并不适用于负载保持的应用。
  • 这里阀的控制形式都是需要操作者用手调节。这里的控制不因被改装,例如安装一个操作杆在已有操作器上。在任何情况下,操作器都不应被其他装置使用。
  • 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。

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.

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

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.
