ZAZME electric sleeve control valve receives direct
current signal from regulation instrument, changing
flow of measured media, and then keep controlled
processing parameters at a given value. it's widely
used in power, metallurgy, chemical, petroleum,
textile, pharmacy, papermaking and other automatic
control systems.
