Pressure rating: 250 psig air.
压力等级：250PS IG中的空气。
They are spool type valves with single or double air pilots with pressure ranges from 0 to 150 psig.
他们阀阀芯型单人或双人空中飞行员从0到150PS IG中的压力范围。
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25ps ig (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 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.
它的故障安全高或低将返回输出到3直接代理模式PSIG中或15 PS IG中的反向代理模式，如果停电，不管逻辑选择。
When the tank pressure reaches 305 psig, a mechanical air-cooled refrigeration unit is activated which cools the tank contents and thereby reduces the pressure to about 295 psig.
当容器压力达到305 psig时，启动机械空气冷却制冷设备，使容器内容物降温，从而压力降到约295 ps ig。
