Electric steam control valve, electric cast steel, high temperature regulating valve, electronic precise and small regulating valve DN125150

The ZDLP and ZDLM electronic single seat and sleeve regulating valves accept the DC current signals from the regulating instrument, and change the flow of the controlled medium so that the controlled process parameters are kept at a given value. Widely used in power, metallurgy, chemical, petroleum, textile, pharmaceutical, paper and other industrial sectors of production automation control.
The nominal diameter of this series is from 20 to 300mm. The nominal pressure is 1.6, 4 and 6.4MPa. The acceptance signal is 0 ~ 10mA.DC or 4 ~ 20mA.DC, and the temperature range is from -40 to 450 degrees centigrade. The electric single seat regulating valve is suitable for occasions where the pressure difference is small, the medium viscosity is large or the particles are slightly impurity; the electric sleeve regulating valve is suitable for occasions where the pressure difference is large and the leakage is large.
