Selection of control valves for pressure swing adsorption units
Thread Content
It takes a few minutes to prepare a set of control valves for a pressure swing adsorption unit; these valves need to be opened and closed once every few minutes, with the switching time being within 5 seconds. The pipe diameter is DN150, and the medium involved is hydrogen gas. The pipeline system uses hot and cold water alternately to raise and lower the temperature, so low leakage levels (Class V) are required. Should a ball valve or a programmable valve be used? I’d like some recommendations for reputable manufacturers
Given the operating characteristics of pressure swing adsorption units, which involve frequent operations, ball valves are not as suitable as programmable valves; it is recommended to let the pressure swing adsorption supplier recommend the best manufacturers. It is the programmable valves that tend to cause problems during the testing phase.
The programmable valves produced by Huaxi are quite good

The programmable valve used in pressure swing adsorption is the most critical moving component of the entire system; the quality of this valve has a decisive impact on the long-term stable operation of the system. It is generally better to have the pressure swing adsorption manufacturers provide the necessary components. At present, several supporting factories in Chengdu are quite good, offering pneumatic or hydraulic solutions for globe valves or triple-eccentric butterfly valves. . . .
Ball valves were used for sequential control in the past. High failure rate; the operation frequency is high this time. Try using a programmable valve
Programmable valves are the best choice; generally, programmable valves are used in the pressure swing adsorption hydrogen production systems manufactured by Huaxi
Why are programmable valves more suitable than other valves, and what are their characteristics? Could any expert give some advice?
I use a pneumatic disc valve for my PSA.
I’ve always wanted to know how good the sealing performance of programmable valves is What is the internal structure like? Could someone explain this to me?
Programmable valves from West China Hospital are still the best – they have a fast switching speed and excellent sealing performance
