Re: Thermal Relief Valve Calculation

Jim:

have attempted to perform same calculation for small piping systems. after consulting with several relief valve manufacturers, they indicated that since my relief volumes were so small the valve would never lift fully. therefore, calculations were unnecessary.

will be interested to see if our group has more tangible information.
