[3dem] Quieting a noisy LN2 tank pressure relief valve?

[Drew Gingerich]

Hello,

Does anyone have experience and/or recommendations for using a muffling/silencing attachment to control noise levels of a pressure relief valve?

We have a 50L LN2 tank with a very noisy pressure relief valve (24 psi limit) that's in the same room as the control station for our microscope. When the valve opens it's both startling and loud enough to hurt our ears, so we're searching for ways to make it quieter.

Thank you for your help,

Drew Gingerich
