● Overview
ZAZP, ZAZN straight electric single seat control valve is DKZ electric unit in the instrument cluster execution unit, which automatically adjust the production process is an important part of the system . It is acceptable to supply power to a uniform or standard signal 0 ~ 10 4 ~ 20mA.Dc, this input signal into a corresponding vertical displacement of the valve is automatically operated to change the opening degree of the valve so as to achieve the industrial medium flow , pressure, temperature, and other parameters of the automatic level adjustment . Which is widely used in chemical , petroleum, metallurgy , power plants and other industrial textile production process and automatically adjusts the remote control .
This series has a variety of standard varieties , bellows sealed , jacket insulation type. Nominal grade products are PN16, 40,64; nominal diameter range of DN20 ~ 400.
