Hi,
I'm looking for suggestions for a suitable Vacuum Breaker(s) for a 30,000 gal. stationary 29% Aqua Ammonia tank. We have had failures with Kunkle, Girard or DFT valves even though they are all 316 SS and suitable for ammonia service. I have looked at Johnson also, but this is located in an enviroment with up to 10 ppm SO2 concentration and the 440 SS ball is not suitable for SO2 service. 2-3" Hg rating would be a bonus.
Any suggestions would be appreciated.
Thanks
