Abstract:
“SINGLE SYSTEM FOR CONTROL OF HIGH OR LOW PRESSURE GASES FLOW RATE AND VALVE FOR CONTROL OF HIGH OR LOW PRESSURE GASES”, consists essentially in a system (S), which has active control of the movement of the valve (1) ram (P) solely by the concept of measurement of the flow rate and by the difference of pressure between the input and output of said valve (1), which, based on certain preconceived parameters, opens or closes the ram (P) so as to compensate the error between the actual and programmed flow rates.
