• 　　 ZDLM electric sleeve regulator receives DC current signal from the regulator, changes the flow rate of the regulated medium, and keeps the controlled process parameters at a given value. It is widely used in production automation control of electric power, metallurgy, chemical industry, petroleum textile, pharmaceutical, paper and other industrial sectors. The nominal diameter of this series of products is from 20 to 300 mm, nominal pressure is 1.6, 4.0, 6.4 MPa, receiving signal is 0-10 mA.DC or 4-20 mA.DC, using temperature range is from - 40 C to 450 C. Among them, the electric single-seat regulating valve is suitable for occasions with small pressure difference, high medium viscosity or slightly particulate impurities; the electric sleeve regulating valve is suitable for occasions with large pressure difference and large leakage.
