I've looked at the orifice plate flow restriction with some different reference material. Used m=.53*Cd*P1*A2/SQRT(T). It appears that the 0.03" orifice will result in critical flow rates on the order of 0.045 lb/min (about 3-4 SCFM) which is within the capacity of the relief valve. I'll...

No - it's pressurizing a water filled tank to transmit the test pressure to a connected detector. Low pressures and low flow rates.

Thanks TD2K. A smaller regulator might work, but considering complete failure of the regulator as an accident condition results in large Cv. The swagelok check valves are good - I used them in a lab environment before - but the current PSV is mounted in a package and I'm trying to minimize...

I ran a test lab, including hydrogen vaporization units, for a fuel cell company. We used swagelok exclusively. Proper joint makeup and avoiding mixed stock (Parker A-lok, etc) are important. The Parker A-lok system is similar to Swagelok and similar in price. Again - the key is not to mix...

I have a low pressure nitrogen gas system supplied from a 3000 psig source through a regulator. The regulator output flows through 6 feet of 1/4" diameter hose to the low pressure components. To limit the low pressure system pressure to 80 psig, the designer used a relief valve. Problem...
