鼻尖到鼻侧自由流 单向阀 带旁路阻尼孔

流量: 120 gpm480 L/min. | 插孔: T-18A
CNJC : 鼻尖到鼻侧自由流 单向阀 带旁路阻尼孔
技术特性 [ + ]

自由流，带旁路节流孔的鼻端孔到侧孔单向阀允许液流从口1向口2自由流动。客户定制的节流孔使口2到口1节流。请参考下面节流孔范围的技术参数。

  • 两口单向阀都是采用相同的孔型，不过需要注意流动的方向有可能相反
  • 1口和2口均可承受5000psi（350bar）的压力。
  • 带有相反液流方向（2至1口自由流动）被当做是流量控制阀，它可在如下地方查阅：固定节流口，无压力补偿流量控制阀带反向单向流量。
  • 客户订制的小孔直径将会在阀体中用数字标出。
  • 抗腐蚀阀是针对腐蚀环境下使用的，其型号通过后缀“/AP”区分（查阅如下可选项）。外部零件是由不锈钢，同时可能的情况下带有钛或者黄铜，内部的零件由碳钢制作，就如同标准阀。如需要知道更详细的信息，请查看结构材料页面。
  • 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

常见问题 [ + ]
I need to discharge a large accumulator. How can I increase the capacity of my discharge circuit?

Because of the very high ratio, the COFO has limited capacity. The discharge path is across a .050 inch (1,3 mm) diameter orifice. If you have large accumulators combined with low precharge pressures, this may not discharge the energy quickly enough. Using the COFO XDN cartridge in conjunction with an LODA XDN will provide capacity for larger applications.

How big is a drop of hydraulic oil?  

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

Direct acting, pilot operated, what do I use?

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.

What parts of the Sun cartridge valve are field serviceable?
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.
