n.表压
Standard pressure settings for saturated steam service are 5 through 15 psig. 对于饱和蒸汽系统来说,标准的压力设置是5至15 psig。
Thrust requirements up to 25,000 Ibs. can be accommodated with standard bore size cylinders assuming minimum 80 PSIG field air supply. 大于25,000磅的推力要求可以通过配置标准镗孔的缸体执行机构来实现，在此假定现场气源压力最小为80PSIG。
This plug of extruded elastomer can be lodged in the throat so tightly that even 2000 psig of pressure will not dislodge it. 突出的人造橡胶会紧紧的堵在喉管处，即使2000psig的压力也不能把它移走。
Carbon dioxide will convert directly from a liquid to a solid if the liquid is depressurized below76 psia (61 psig). 如果液体压力降到76psia(61psig)以下，直接从液态转化到固态。
Turndown 10 to 1 with low pressure gas.Turndown 16 to 1 with 10 PSIG (700 mbar). 使用低压燃气时调节比可达10比1，使用10PSI的高压燃气时调节比可达16比1。
