It is suitable for high pressure gas cylinders and pressure relief
gas supply on both sides, through the automatic changeover to
realize continuous gas supply, with the function of purging.The
maximum input pressure of 20.7Mpa (3000psi), corrosion, clean
workshop assembly test, suitable for laboratory, high purity gas
such as gas analysis. | pressure specification of semi automatic switching system | | 1 | max. inlet pressure | 3000,2200psi | | 2 | max. inlet pressure | 25,50,100,150,0~250psi | | 3 | working temperature | -40℃~74℃(~40℉~165℉) | | 4 | leakage rate | 2x10-8 atm.cc/sec He | | 5 | Cv | 0.14 |
