Re: [PSUBS-MAILIST] ambient ballast control

Dan,
Granted you have open bottom tanks but if they were closed and you had a regulator failure with an almost full ballast tank, your tank would probably then rupture.
Respectfully,
Jay K. Jeffries



Why would you need a relief valve in a ballast tank if it is built to withstand the pressure of the system? 
 
My Main ballast tanks are open bottom and don't need a relief valve and my main ballast tank is built far strong enough to withstand my 175 PSI system pressure.  Unless your dealing with a compressor that may not shut off and run to high, where is the need for a relief valve?
