having now finished the pcp conversion to my king ratcatcher i find that the valve that existed from the co2 setup is not very consistant at the higher pressures, and the question is does anyone have the lowdoen on self regulating single stage valves i assume it is to do with the fact that as the air is used the valve is easier to knock open thus allowing more air through as the pressure drops but i am not sure so any advice much appreciated incidently the max pressure is 2000 psi big rsevoir though so should be ok.
