The ZDL series electronic formula goes nonstop to the regulating valve (saying that electrically operated electrically operated regulating valve) is in the electrically operated unit combination measuring appliance's execution unit. He accepts from regulation meter's direct current signal, the direct change is adjusted the medium the current capacity, causes to be accused the technological parameter (for example temperature, pressure, current capacity, fluid position and so on) maintains at the given value.

    This serial products structure is simple, the volume is small, the weight is light, the valve chest modern design, the valve capacity is big, the resistance to flow is small, the rated flow coefficient is big, correction convenience and so on. The electrically operated regulating valve and the pneumatic valve compare, have the movement to be keen, the energy uses conveniently, the signal transmission is away from and so on far rapidly with the transmission, thus it widely applies in the chemical industry, the petroleum, the metallurgy, the power plant, the light industry, the drugs manufacture, the papermaking and so on various Industry sector's production automation, the depth is welcome the domestic and foreign users.
