ERWX electric soft seal butterfly valve product knowledge

Product Features ERWX pneumatic soft seal butterfly valve operating torque is small, is the smallest operating torque in all valves, is the automation control system instrumentation unit, with AC220V, AC380V or DC24V power supply voltage to power from (DCS, PLC ) System or regulating instruments, operators and other input (4-20mA, 0-10mA or 1-5VDC) current signal or voltage signal, you can control the operation. Rotate the valve shaft by 0 ~ 90 ° with the torque output from the angular stroke to complete the opening / closing action or the adjustment action. All-electric electric actuator adopts the mechatronic structure, with the functions of position feedback, position indication, manual operation and other functions in the machine servo operation and opening degree signal, strong function, reliable performance, simple connection, precise control, small size, weight Light, small flow resistance, large flow coefficient, simple structure, good sealing performance. Adjust the range, through the input current signal or voltage signal, this into a displacement corresponding to the input signal, change the rotation angle of the valve plate (0-90 ° any angle), so a certain input signal corresponding to a certain corner, to achieve Proportional action, so there is a better regulation of control flow and other parameters.
