Tianjin Actuator,Bell Valve Actuator,Bell Actuator,
motorized valve actuator
The electric actuators we manufactured are the products by using the introduced advanced technology from BERNARD Company of France.
It has various kinds of protection function and control mode. It can be divided into the quarter-turn series, linear-turn series and multi- turn series. There are more than hundred kinds of specifications. Its control main board is continuously upgrading and updating and the new products appear rapidly in order to satisfy the needs of modern industrialization.
The electric actuator has already widely applied in the large and medium-sized project which is the newly built and was highly appraised by users.
At the same time, we also accumulate rich technology and scene experiences in the process of updating and upgrading DKJ or other actuators to the introduced series.
Principle of work
The DKJseries electric actuator are the terminal control device of industrial process survey and the control system, changing the system’s control signal into angular displacement, linear displacement of output axle, the position of valve and other regulating units. The main purpose is to enable the controlled medium to work well under the regulated system conditions.
The electric actuator is divided into the proportion type and integral type according to the controlling type. The proportion actuator is made up of electric servo amplifier and integral type actuator that can compare systematic control signal with the feedback signal (closed-loop control) of output axis so as to change the travel route and has proportion relations with the output axis signal. The integral actuator consists of servo motor, reducer and position transmitter. Coordinating with motor operator, it can control valve or other regulating units from long distant.
