The product characteristics of pneumatic sealing butterfly valve

ERWX pneumatic sealing butterfly valve operating torque is small, is the smallest of all pneumatic valve control moment in class a, is the instrument automation control system of execution unit, with ACV, ACV or DCV listed listed power supply voltage for the power, from ( DCS, PLC) System or instrument to adjust, and operator input ( - mA、- MA or - 伏直流电) Current or voltage signal, can control operation. To Angle the itinerary output torque of rolling pneumatic valve shaft ~ °, opening and closing action or adjust the action will be finished. All electronic electric actuators, adopting the structure, mechanical and electrical integration with machine servo control and opening position feedback signal, position indicator, manual manipulation, and other functions, functional, reliable function, simple attachment, control precision, small volume, light weight, small flow resistance, flow coefficient, simple structure, good sealing function. The adjusting range is big, through the input current or voltage signal, and turn this into the displacement of the input signals corresponding to the change of the pneumatic valve plate rotation Angle ( - ° at any Angle) , so some input signal corresponding to a certain Angle, realize the proportional action, therefore better adjust the control parameters such as flow.
