Answer / sr
i guess this is a simple question ... i will ask something different ... i/p output is 3-15 psi ... and our bench set or spring range is higher many times like 6-30 psi ... how 15 psi pressure will give enuf back pressure to give 30 psi ???

Answer / gautam
As we know the pressure is equel to the ratio of the force to area,in control valve having diaphrams where it convert pressure to displacement..diaphrams size in air chamber should measure and pressure is given so we can calculate the force..
