Description：

A brief introduction:
ZAZP seriesThrough single seat electric regulating valveThe DKZ series electric actuator and straight through single seat valve is composed of two parts, the single-phase AC 220V power supply for power, take 0 ~ 10mA or 4-20mA DC signal, automatic control valve opening, continuous adjustment of the fluid in the pipeline pressure, flow, level and other parameters of the.The product is sensitive, convenient and energy characteristics of fast signal transmission.Widely used in electric power, metallurgy, chemical industry, textile and other industrial automatic control system.
