Better to have 75% working instead of 100% in a more critical situation.
This evolution of Moki makes absolutely sense in everydays use..
No you are wrong, the pulse pressure never reaches the butterfly valves, it stays in a separate diaphragm chamber
Also the 3 and 4mm 25% is from caliper measurement and the 40% is from pressure gauge measurement, I don't know why they don't correlate, but the sinus function is involved here.. crank movement..
