The Pressure Analyzer is a tool for calculating pressure regulator output. It allows you to consider different springs and boost valves and then allows you to calculate regulator pressure output through a range of EPC/TV pressure input. It works with valves having only one reaction area and those with two.
Begin by entering the reaction diameter(s) of the regulator valve. Next, enter the spring force (at its working height). The working height is the height at which the spring is compressed while the valve is regulating. If you’re unable to measure the valve’s working height use the optional method, though it’s less accurate. Measure line pressure in neutral with ZERO EPC/TV pressure and enter it in the “Pressure Regulator Output” field; The program will calculate the spring weight. Now you can use a scale and caliper to compress the spring to that weight and measure the height.
Now enter the remaining valve dimensions in the system (reverse and EPC/TV boost). With this data, the program will calculate regulator pressure at zero EPC/TV pressure all the way through maximum (generally 90psi or so). If the system you’re testing has different boost valves and springs available you can substitute them into the program and calculate regulator pressure output.
Once you've input all teh data you can use the Pressure Graph to draw the pressure rise through it’s entire range.
