proper valve

Electrical wiring should conform to NEMA codes to assure proper valve operation and longevity.

电源线应该符合美国电气制造者协会NEMA规程,以确保正常的阀门工作状态和使用寿命.

Repeat steps 2-5 until proper sag is achieved , then replace the air valve cap.

重复2 - 5步骤以达到最佳预压行程后, 盖上气阀嘴帽.

The proper application of the elastic material with the filter measure can improve the performance of durableness and the performance against blocking of the solenoid valve considerably;

弹性材料的恰当应用再辅以过滤措施，又可大大提高电磁阀的防卡耐用性能；

In order to select a proper piezoelectricity valve for the gas injecting system on Sino UNIted Spherical Tokamak ( SUNIST), we have tested the gas injecting rate and pulse response of NS valve ( made in China) and VEECO valve ( made in USA).

为了给中国联合球形托卡马克装置（SUNIST）的充气系统选择合适的压电阀，我们对国产NS型压电阀和美国的VEECO压电阀进行了送气率和脉冲送气特性的测试。

Reference Figure 1 and Figure 2 for proper valve orientation.

关于正确的阀门定位,请参考图1和图2.

Be sure to use proper valve material-types for both temperature and chemical resistance.

确保采用与温度和耐化学性相匹配的材质的阀门.
