Programmable valve for pressure swing adsorption
Thread Content
Is there an effective solution for internal leakage in the programmable valves used in pressure swing adsorption PSA systems?
Under normal circumstances, it can only be taken offline for maintenance; otherwise, the purity of the product will be affected
Have Cheta handle the repair; if it can’t be repaired, then replace it with a new programmable valve!
Try increasing the hydraulic oil pressure; otherwise, if the seal is damaged, it will have to be repaired
The cause of the damage should be investigated; I have no experience with this type of equipment. Is it because there are too many impurities? ?
PSAs generally do not come equipped with single-tower isolation valves; in such cases, shutdown is the only option. It is advisable to first determine which valves are leaking. If the leakage has little impact on the product, maintenance can be carried out, making sure to purchase the necessary parts in advance
You can try adjusting the screw that controls the degree of closure; it’s possible that it isn’t closed fully or has been closed too much
