What material valve should be used under these operating conditions?
Thread Content
The valve here is used to control the regeneration of the adsorption tower; the regeneration is carried out using steam, which is saturated steam containing a certain amount of moisture. The valve that controls steam inflow is fine, but the valve that controls the exhaust gas outlet after steam regeneration leaks severely; air leaks from two gaps as well as around the rotating shaft, and tightening the screws to stop the leakage through those gaps doesn’t work. The steam temperature is around 200°C; to control the steam flow, the valve is opened only by a small angle (approximately 45°). After checking the composition of impurities in the feed gas: alcohol
Thank you for your reply, but what is the basis for this? What kind of medium is it, or has the mixing of these media resulted in a new corrosive medium?
Thank you for your reply. What is the basis for this? Which type of medium has strong corrosivity?
