electric flanged tri-eccentric butterfly valve

Electric flanged tri-eccentric butterfly valve is simple in structure, small in size and light in weight, and consists of only a few parts. When the electric flange butterfly valve is in the fully open position, the thickness of the disc is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is small, so it has better flow control characteristics.

The electric flange butterfly valve mainly has three structures of three eccentricity and single eccentricity. The sealing form includes metal seal, PTFE seal and rubber seal. The metal sealing structure is mainly suitable for working conditions above ≥300 degrees; the PTFE sealing structure is suitable for working conditions within ≥180 degrees; the PTFE sealing structure is suitable for working conditions within ≥120 degrees; the electric flange butterfly valve is equipped with The angular-stroke electric actuator can directly receive 4~20mADC or 1~5VDC control signals output from computer or industrial instrument, and intelligent step adjustment (PID) is performed on the actuator drive motor according to the deviation of the valve position feedback signal and the set value. Adjust) to achieve accurate positioning of the valve or other device with the actuator, and output the position feedback signal of 4 ~ 20mADC. At present, electric flange butterfly valves are widely used in petroleum, chemical, metallurgy, light industry, papermaking, power station, refrigeration and other work fields.
