High-temperature breather valve
Thread Content
I would like to ask the experienced colleagues here: I have a storage tank filled with water, and the water temperature is around 90 degrees. Is there a suitable vent valve for such temperatures? We replaced several breathing valves; the gaskets didn’t last even half a year before the breathing valves started to hiss
Since it’s water, a breathing valve isn’t necessary. Gaskets can be metal-graphite gaskets or PTFE gaskets.
The water temperature fluctuates between 50-90°C on a daily basis, the water volume remains constant, and there is nitrogen sealing in place. Our gaskets at the moment are made of stainless steel coated with PTFE, and over time the PTFE deforms.
