For nitrogen sealing of methanol dome storage tanks, are self-regulating valves effective?
Thread Content
Everyone: Is the nitrogen seal self-regulating valve effective? Can it adjust itself? As soon as we opened the stop valve, nitrogen flowed in, and air came out from the tank’s vent? How to calibrate a self-regulating valve, and how often should it be calibrated!
It works well, but it’s necessary to choose the right model. My design specifies a pressure range of -200 to +500 Pa; it operates normally. The product is calibrated upon leaving the factory, and no further calibration is needed in daily use, with pressure monitoring at the top of the tank being sufficient. Any adjustment must be carried out by the manufacturer.
Could any friend provide the nameplate or parameter sheet for the self-acting regulating valve used for nitrogen sealing in methanol storage tanks?
