The working principle of electric pneumatic control valve is introduced

Electric pneumatic regulator is connected by electric actuators and pneumatic - valve combination after mechanical connection after assembly, commissioning the installation of electric pneumatic control valve. Electric pneumatic control valve working power supply: DC24V, AC220V, AC380V voltage grade, etc. Electric pneumatic control valve is an important execution units in industrial automation process control instrumentation. As in the field of industrial automation degree is higher and higher, is being more and more application in the field of all kinds of industrial production. Industrial automation control system of electric pneumatic control valve by receiving signal, Such as: 4 ~ 20 ma) To drive change valve core and valve seat between the cross-sectional area of the pipeline medium size control of process parameters such as flow rate, temperature, pressure and etc. Automated regulating function.
