Working principle of Electric Control Valve
Mar 19, 2020
Working Power Supply: DC24V, AC220V, AC380V and other voltage levels. Input Control Signal: DC4-20MA or DC1-5V.
Feedback Control Signal: DC4-20MA (load resistance less than 500ohm) controls the flow, temperature, pressure and other process parameters of pipe media by receiving signals from industrial automation control system (E. G. , 4-20mA) to drive the valve to change the cross-sectional area between the valve core and the valve seat. Realize the function of automatic regulation. The new type electric control valve actuator includes feeding function, accepts the unified 4-20mA or 1-5v DC standard signal, transforms the current signal into the corresponding linear displacement, automatically controls the regulating valve opening, the pressure, flow rate, temperature and liquid level of the fluid in the pipeline can be adjusted continuously.
