鼻尖到鼻侧自由流 单向阀
自由流，鼻端孔到侧孔单向阀为开/关液路元件，它允许液流从进口（口1）向出口（口2）自由流动，截止其反向液流。
- 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
- 单向阀具备非常低的泄漏等级，其中最大泄漏量每分钟少于1滴（0.07cc/min。）
- 1口和2口均可承受5000psi（350bar）的压力。
- 配置EPDM密封圈的插装阀用于磷酸酯液压油系统。暴露在石油基液压油或润滑油脂中会损坏密封圈。
- 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。

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.
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.
