Product characteristics of pneumatic sealing butterfly valve (3)

ERWX air sealing butterfly pneumatic valve operating torque, which is all of a minimum of a pneumatic valve operation is a instrument automation control system of the execution unit, and the ACV, listed from (ACV or DCV listed power supply, and accept DCS system and PLC) System or adjust the instruments, operators and other inputs ( - MA, - MA or - V dc) Current or voltage signal to control the operation. The output torque of rotating pneumatic valve spindle rotation? °, can complete opening and closing action or adjust the action. All electronic actuator, the use of mechanical and electromechanical integration structure, with the machine operation and open servo position feedback signal, position indicator, the function such as manual operation, powerful, reliable performance, simple connection, control precision, small volume, light weight, small flow resistance, flow coefficient, simple structure, good sealing performance. Adjusting range, through the input current or voltage signal of the signal, it become a pneumatic valve plate to change the rotation Angle displacement of the corresponding input signal ( - In any Angle °) , so the corresponding input signal, to a certain Angle, realize the proportional action, this is the flow parameters such as better management and control.
