High pressure electric control valve Feature

High pressure electric control valve is used for high pressure high temperature boiler steam steam, High pressure electric control valve is composed of a DKZ type series of straight travel electric actuator and through single seat control valve is composed of two parts, with the single phase AC 220V or DC 380V power supply for power, accept 0~10mA or 4~20mA DC signal, automatic control valve opening, continuous regulation of pipeline fluid pressure, flow, level and other parameters. High pressure electric control valve is sensitive, convenient use, energy and signal transmission characteristics of rapid. High pressure electric control valve is widely used in electric power, metallurgy, chemical industry, textile and other industrial automatic control system.
