4~20mA Sleeve type high pressure electric control valve

4~20mA Sleeve type high pressure electric control valve

Short Description:

ZAZM Sleeve electric control valve is composed of a DKZ type series of straight travel electric actuator and through sleeve 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. ZAZM Sleeve electric control valve is sensitive, convenient use, energy and signal transmission characteristics of rapid. ZAZM Sleeve electric control valve is widely used in electric power, metallurgy, chemical industry, textile and other industrial automatic control system.
