RE: ASME rupture disc

You must use two rupture discs, each with a backing support to they will only rupture in one direction,

RE: ASME rupture disc

Hi Laurent,
I am not aware of any bi-directional discs on the market that are ASME certified.  Additionally, I don't think there are any sanitary rupture discs that go down to 3 psig that are also ASME certified.  I really do think your only option here is to use an ASME certified vacuum breaker in conjunction with a sanitary rupture disk like an Axius SC on the website mentioned above.  If you find another solution I would love to hear about it.  Good luck!
