     Used in PSA oxygen generating device. High purity oxygen is obtained by using molecular sieve to selectively adsorb carbon dioxide, water and impurities in air under normal pressure. There is also VPSA method. Requirements for valve are fast on/off speed, long working time and good sealing performance. High performance pneumatic butterfly valve, which has reliable performance, can open and close one time in an adsorption cycle(about 40 seconds), it operates a million times one year.
