Thermal relief valve is somewhat different than the regular relief valves as it is not meant to full relief instead, it fulfills the purpose of relieving a small volume through the valve enough to bring the pressure down that was increase due to the trapped liquid inside the pipe due to expansion caused by the ambient temperature.
This software is developed with great precision and care to accurately determine the required orifice size of PSV. Selection of different types of PSV, back pressure, set pressure and over pressure range can be defined in the input section. User can print out or save the application results in PDF file.
The result section gives complete information on all the sizing constants, mass flow rate and size of orifice.
Errors and program limitations are cautioned through message bar on the screen.

Software is compatible to install and run on Windows 95-2000, Windows XP, Windows 7 and Windows 8.
