Product Description

Product Overview

DWZ rotary modular multi turn electric actuator is a very important field driving device in the industrial process control system. Its energy is convenient to use, simple to install and debug, and is increasingly widely used in electric power, metallurgy, petroleum, chemical and other industrial sectors. The electric actuator consists of electric actuator and regulating valve. The control accuracy mainly depends on the control performance of the electric actuator. It can convert the control signal of the system into angular displacement and linear displacement of the output shaft, the position of the control valve and other interceptors or other regulating mechanisms, so that the controlled medium can work according to the system requirements

Product characteristics

Waterproof performance: the key part adopts non through magnetic induction, and the lens part adopts sealing rubber ring, reducing the possibility of water entering from the outside.

Access mode: Non intrusive access mode without opening the cover is adopted to reduce the possibility of water entering the box due to incorrect operation by on-site workers

Intelligent switch integration: intelligent switch adjustment integration reduces the pressure of purchasing and stocking. (Password is required for switching modes)

Encryption mode: to prevent misoperation of field workers, which may lead to error of module parameters and damage of valve body.

Precision: high precision, up to 1% precision, and the basic error is not more than 1%.

Module self-protection: automatic phase discrimination and commutation function, power input phase loss detection, motor overheating, instantaneous turnover, power failure, overload fault alarm, current input and output over-voltage and over-current protection, and anti-interference protection of all models.

Customizable: special voltage, extended field bus (Modbus Rtu, Profi bus communication protocol, special protocol), input and output signals, shape structure, special module, English module.
