Disadvantages of electric control valve
Oct 12, 2018

Electric control valve is also not without defects: the heat generated by the motor operation will lead to thermal protection, so that the control valve to stop working; Because the motor must be multistage deceleration to output torque, so the speed is not fast, in some requirements for rapid opening and closing of the occasion is not applicable, vigorously and high-speed, or a more difficult to resolve the contradiction , because of the number of moving parts, relatively easy to produce faults, especially in the regulation of frequent working conditions, easy to generate motor thermal protection, deceleration gear damage, module SCR burning failure, in this case, it is best to choose pneumatic control valve is more appropriate.
