ZPD-0121 Type Electro-Pneumatic Valve Positioner

Zpd-1000 series electric valve positioners supplied by Changyang instruments include: zpd-01; zpd-02; zpd-0121; zpd-0122; zpd-1111; zpd-1112; zpd-1121; zpd-1122; zpd-1211; zpd-1221; zpd1000 series electric valve positioners are one of the industrial automation instrument varieties, and are the main supporting instruments of pneumatic actuator (pneumatic control valve). It is used to overcome the unbalanced force caused by the pressure difference of the control valve and improve the linearity of the valve position, so that the stroke (valve opening) of the regulating valve is proportional to the current signal of 4-20mA or 0-10madc output by the regulating instrument, so as to realize the correct positioning.
