The overall control electric actuator (WK) is based on the D ZQ 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.
Key performance parameters
Power supply AC380V50Hz three-phase and three-line system.
Valve position signa output 4 ~ 20mA (0~ 20mA)
Level of protection IP67
Environment temperature -20 ℃ ~+ 60 ℃
Output power 0. 030~ 15kW
Operation 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 l uminescent 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.In the process of opening the valve, the red light flashes and the green light is on,In the process of closing the valve, the green light flashes and the red light is on,The valve is in the fully open position, the red light is on and the green light is off, The valve is in the fully closed position, the green light is on and the red light is off.After the local operation, press the remote button to switch to the remote operation state.
