技术特性 [ + ]

此阀是3位4通比例方向阀。中位时,口2和口4接通口5泄油而口3关闭。口1先导压力抵抗弹簧力会在口3到口4方向上形成一个与口1压力大小成比例的可变节流口。口6的先导压力打开口3到口2流道。液动力,弹簧力和先导压力平衡下会使此阀随负载压力变化而产生一定程度的自补偿效果。口1和口6的压力直接相互抵抗。

  • 对于1口和6口的运行压力一般不应超过500psi(35bar)。
  • 这些阀或许需要通过外部调节逻辑阀提供压力补偿。对并联回路采用LR*C-XHN,或者对于节流回路采用LP*C-XHN。
  • 这款阀提供一定程度的自我补偿,可以用于流量控制。为提高流量控制的精准度,外部的逻辑调节阀可以用来保证大范围流量和压力情况下稳定的流量。可参考附加信息中的曲线。
  • 口1和口6之间相互直接作用。
  • 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

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.
