4-20ma valve actuator with electric butterfly valve ags-400 ags-400a ags-400f ags-400p ags-400r

The integrated intelligent electric actuator adopts advanced intelligent digital control technology, which can directly receive 4~20mADC signals from industrial control instruments or computer outputs without additional feedback unit and servo amplifier. It enables accurate position control for a variety of industries such as ball valves,butterfly valve. dampers, baffles, couplings and more. The product not only improves the accuracy of the position control of the electric actuator, but also realizes miniaturization, intelligence, and integration (the controller and the actuator are integrated). Compared with the traditional electric actuator, the product has the characteristics of small size, light weight, high precision, strong function, reliable performance, low running cost, no maintenance, etc. It can be widely used in power stations, petroleum, chemical, metallurgy, Medicine, light industry and other industries.
