FIELD: machine building.
SUBSTANCE: system consists of control circuit, turning controller of valve on, of converter of "current-pressure", of control valve and of valve drive connected with gate of control valve, and of filter of valve opening lead-delay connected with input of control valve. Short-time reference signal of control is transmitted to input of control circuit for overload of input signal of control in circuit of amplification in forward direction of the control circuit or in the converter "current-pressure, thus generating an output signal actuating motion of the valve gate. Regulated, set by a user input characteristics at input of the filter of valve opening lead-delay connected with input of the control circuit facilitate achieving set response of the control valve at input of small amplitude.
EFFECT: improved control valves functioning.
