380v electric actuator linear 220v SKZ-5100/K/F SKZ-5200/K/F SKZ-5300/K/F SKZ-5400/K/F SKZ-5500/K/F
DKZ series 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.

On-off type electric actuator
On-off type electric actuators generally control the opening or closing of the valve. The valve is either in the fully open position or in the fully closed position. Such valves do not require precise control of the medium flow. It is particularly worth mentioning that switch-type electric actuators can be divided into split structures and integrated structures due to different structural forms. This must be explained when selecting the type, otherwise it will often occur in the field installation and the control system conflicts and other mismatches.
On-off type electric actuators are also known as open-loop control type electric actuators. These actuators only have two actions of opening and closing when performing valve operation, that is, the valve can only be fully open or fully closed. on-off electric actuators do not control the amplitude of the valve on-off and do not allow precise control of the media flow.
Regulating type electric actuator
The regulating type electric actuator is also called the closed-loop control type electric actuator. In addition to the control function of the valve switch, the actuator can precisely control the opening amount of the valve to achieve precise control of the medium flow. Regulating electric actuators are divided into electric open type electric actuators and electric off type electric actuators in terms of working form. The working control signals of the electric open type electric actuator and the electric on off type electric actuator are different. The working form of the electric actuator should be determined during the selection, otherwise it is not suitable in the control system and is difficult to modify. The regulating electric actuator is equipped with loss of signal protection. When the actuator cannot receive the signal due to line fault or other reasons, it will automatically open and close the control valve to the established state, usually the valve is fully open, fully closed or kept in place.
