1. 0-360°rotation angle
2. It can be used to control gate valves,globe valves as well as high temperature and high pressure valve and desuperheater water valve or other control valve to be rotated multiple-turns
3.Modbus Hart Profibus
The overall control electric actuator (WK) is based on the D Z/Q W switching electric actuator. Adding the electrical control part, namely WK 2 power control part, which integrates mechanical transmission and electrical control, with the function of field operation and remote operation control, the field debugging is very convenient, which is suitable for all kinds of open loop control system. Valve for switching operation and control.
The electronic control part is composed of thin film key panel, function board, power supply and plug board and ac contactor. The plug-in and fastening bolts and electric actuator connection can be easily disassembled or replaced.The electronic control part is composed of thin film key panel, function board, power supply and plug board and ac contactor. The plug-in and fastening bolts and electric actuator connection can be easily disassembled or replaced.
Key performance parameters:
Power supply: AC380V50Hz three-phase and three-line system.
Valve position signal: output 4 ~ 20mA
Level of protection: IP67
Environment temperature: -20 ℃ ~+ 60 ℃ Output power: 0. 030~ 15kW
WK can operate in "remote" or "in-place" respectively. When the power is switched on, it is in a "remote" state. The "in-place" operation button does not work. If the "in-place" operation is required, the lower cover of the panel should be opened. Click on the "in place" button to switch the "remote" state to "in-place", when the "distant" status indicates green. The color luminescent tube is extinguished, the red light emitting tube is bright in the "in-place" state, and in the remote control room, "remote operation indicator light" Put out, the "open, close, stop" button of remote operation does not work, can only operate on the local operation panel "open, close, stop button.
Note: the valve position indication signal of WK is used as signal sensor components. In the actual debugging process, due to the different travel range of the signal gear assembly, the POT is made. The rotation direction is either clockwise or counterclockwise for two conditions, during valve adjustment, manual or electric operation is performed. The mechanism is in the "full clearance" position, and the rotating direction of the potentiometer POT is observed. If the potentiometer is not in the terminal position, it can be taken the potentiometer is rotated to the terminal position according to the rotation direction observed above, if the current value is not shown in the current meter at zero and potentiometer to the direction of rotation, less current, at this time exchange the two ends of potentiometer A5, C5 at these two core terminal (terminal lumen is in the control of the electric actuator ontology.
