This valve is installed in the iron and steel metallurgy system of hot blast stove, heating furnace, heat exchanger, such as dust catcher system of cold air, gas, air and flue gas pipeline, have the effect of regulating medium flow. Can also play the role of large truncation medium, to reduce the pressure.
When the baffle opening within 90 ℃ schedule change, through the line of working medium flow rate and pressure head also is linear change accordingly, linear adjustment characteristics of damper is good, operation is stable and reliable.
Electric shutter valve features:
Shutter, the structure of the shaft, shaft adopts modular structure, easy to maintenance. Sealing filler adopts flexible graphite, sealing pressure is adjustable, valve plate streamline structure, small flow resistance, uniform flow, open-close torque is small, action quick, reliable in performance.
Tilt electric shutter valve working principle:
Electric actuators through the crank and connecting rod drive the valve leaf axis synchronous rotation control valve opening, adjust the flow line.

Working principle and structural features:
This valve is a vertical plate with regulating valve features, Venetian blinds, shutter panels, valve by valve body, linkage mechanism, main components, such as electric actuator are all welding structure, the shaft end using the flexible graphite braided packing seal, high temperature resistance. Shutter panels of the opening and closing by the handwheel or motor drive Z series electric actuator, electric actuator output through level of worm gearing to final output shaft torque transmission to the valve, valve spindle rotation drive linkage, enables multiple louver board synchronous rotation, to change the pipe sectional area, to adjust the medium flow rate, large area of cutting medium or reduce the effect of medium pressure, adjust the Angle of 0-90 °.
