OK, China
My fx crown has encountered an unsolvable problem.





Transmission port .25 / .30



Reg / 135ban spring force MAX 15.5mm 835f / ps 836 832



Reg / 130ban spring force MAX 15.5mm 869f / ps 866f / ps 867f / ps



Reg / 125ban spring force MAX 15.5mm 879f / ps 876f / ps 877f / ps



Reg / 120ban spring force MAX 15.5mm 915f / ps 913 919



Based on this data, I have a problem. The higher the pressure set by the regulator, the lower the speed, which is not normal.
 
Somethings metrics do well, others not so much. 5 bar = 72~ Pounds per square inch (psi)... So if you increase the BAR you increase the force holding the valve shut. The hammer energy will have to be increased to hit the valve stem hard enough to have equal lift compared to lower Set Points...



The opposite applies when lowing set point..you require less hammer energy to open the valve as much as a higher set point because LESS force is holding the valve shut.

Is pretty normal if you know how it work, more pressure need more force to open the valve. All of the above!
