Self-acting pressure reducing valve
Thread Content
Regarding self-acting pressure relief valves for nitrogen protection in atmospheric-pressure storage tanks, which domestic brands are the best? Which is the best fire-resistant breather valve for use with it? What about the imported ones? How to choose a model? What parameters should be considered when making a selection? Please ask the experts for help.
Self-acting pressure regulator: pressure before the valve, pressure after the valve, pressure difference, maximum and minimum normal flow rates, pipe connection sizes, pipe material, medium, temperature. Flame arrester: medium (whether it is a chemical mixture), stability of chemical properties, explosion protection rating, maximum operating pressure at the installation location, minimum and maximum operating temperatures at the installation location, allowable maximum pressure difference, maximum flow rate, connection pipe size, connection pipe material. Device features: Design – whether there is deflagration at the end of the pipe, short-term combustion, or continuous combustion? Is there deflagration inside the pipe? Stable explosion, unstable explosion, unidirectional, bidirectional? Flame distance: Is there a flame on the flame arrester? Connection method, pipe material?
