its fail safe high or low will return the output to 3 psig for direct acting mode or to 15 psig for reverse acting mode if the power is lost, regardless of the logic selected.
containers used for transporting liquid nitrogen at pressures greater than 25 psig (40 psia) need to be designed, manufactured, and tested to dot specifications.
用于运输压力大于25psig (40psia)的液态氮的容器需要按照dot规范设计、制造和检测。
its fail safe high or low will return the field reversible output to 3 psig for direct acting mode or to 15 psig for reverse acting mode if the power is lost, regardless of the logic selected.
medium-pressure valve provides leak-free seal for pressures up to 15,000 psig (1034 bar) of the applications, the design is the entire pressure range so that it can provide a more consistent seal.
