it means the spring in side the gov has been pushed up by the pressure of the mains gas and has locked the gov normally done when doing a tightness test and pushing the control arm to fast
above 23mb is the standing pressure at the meter
when a gas appliance is turned on this is the working pressure
Is governer another word for the regulator?
Does it push the spring so it locks open or shut?
