8100A type electric pneumatic valve positionerDetailed product description：

The 8100A electric pneumatic valve positioner is the latest developed product based on the digestion and absorption of imported technology. Like other Type III signal positioners, it is a commonly used supporting instrument for pneumatic control valves. After receiving a 4-20mA DC electrical signal, it outputs a certain pressure signal to control the valve stroke. Through a feedback system, the valve stroke changes proportionally with the input current signal, ensuring the correct positioning of the valve.

The 8100A electric pneumatic valve positioner is designed in accordance with the electrical safety regulations for explosive hazardous areas and the requirements of GB3836 "Explosion proof Electrical Equipment for Explosive Environments" standard. It is of the quality and safety type (with the explosion-proof symbol ia Ⅱ CT6) and the explosion-proof type (with the explosion-proof symbol d Ⅱ BT4), and is suitable for explosive environments in Zone 0, Zone 1, and Zone 2, respectively.

The 8100A electric pneumatic valve positioner is divided into two categories based on its structure: lever type and cam type. It is equipped with linear pneumatic thin film actuator, ∑ F pneumatic actuator, and 35002 eccentric rotary valve, respectively. It can overcome the friction force of the valve stem, eliminate the unbalanced force of the regulating valve, improve the accuracy of valve position, increase the action speed of the valve, and achieve split range control. Therefore, it is widely used in automatic control systems of industrial sectors such as petroleum, chemical, metallurgical, power station, and textile.
