Description
Product Introduction: 8100A electric valve positioner is a newly developed product on the basis of digestion and absorption of introduced technology. It is the same as other type III signal positioner. It is a commonly used instrument for pneumatic regulating valve. Through the feedback system to make the valve stroke and input current signal proportional change, so as to ensure the correct positioning of the valve.
8 100A electric valve positioner is designed into intrinsically safe type (explosion-proof mark is ia lI CT6) and flameproof type (explosion-proof mark is d Il BT4) according to the electrical safety regulations for explosive dangerous places and the requirements of GB3836 "explosion-proof electrical equipment for explosive environment" standard. They are suitable for explosive environment in Zone 0, Zone 1 and Zone 2.
8100A electric valve positioner according to the structure is divided into lever type and CAM type two categories, respectively with direct travel pneumatic thin film actuator, ∑F pneumatic actuator and 35002 eccentric rotary valve, etc., can overcome the friction of the valve stem, eliminate the influence of the unbalanced force of the regulating valve, so as to improve the precision of the valve position, improve the speed of the valve and realize the division control, Therefore, it is widely used in automatic control system of petroleum, chemical industry, metallurgy, power station and textile industry.
