Low Pressure Vacuum Vant Valves

[JAlton]

I am looking for guidance in the Testing of Low Pressure Vacuum and Vent Valves (weight loaded and spring loaded). These are below minimum for ASME Code Rules. I need Set Pressure Definition, Test method, Set Pressure Tolerance, Gauge Accuracy, etc. Also Seat Tightness requirements. Any help would be appreciated. Thanks.

If I can get some soup off you, I'll let you know a secret;- if you google the wolds tank vacuum pressure valves, you can get all the info you need, plus the contact number to talk directly to the valve manufacturers, to ask for their testing specifications.
cheers,
