Electromechanical valve electric device DZW60-24-A00-WK;
Valve valve: gate valve, cut-off valve, regulating valve, slurry valve
The switch type is suitable for operation of valves such as gate valves and globe valves. The protection level is IP55 (lP65), the output torque range is 50-10000Nm, and the output speed range is 12-36rpm.
The main models are: DZW10-18-A00-WK, DZW20-18-A00-WK, DZW30-18-A00-WK, DZW45-18-A00-WK,
DZW60-18-A00-WK, DZW90-18-A00-WK, DZW120-18-A00-WK, DZW180-18-A00-WK, DZW250-18-A00-WK and so on.
First, an overview
The whole control valve electric device (hereinafter referred to as WK) is the basis of electric device switch in DZW, increase the electrical control part, namely WK type power control, mechanical transmission and electrical control together with on-site operation and remote operation control functions, debugging is very convenient, suitable for switch operation and control of the various types of valves in the open loop control system. The electronic control part is made up of membrane key panel, function board and AC contactor. The electric control part is connected by plug-in and fastening bolts and electric devices, so that it can be easily disassembled or replaced, and separate control can also be realized.
Two. The main technical parameters

Three. Operation
WK were in the "distance" or "local" state of operation, when in the "distance" of each state after the power is switched on, if the need for "local" operation, click "local" button will switch to the "remote" state of "local" state, at this time, the "distance" of the green indicator the luminous tube is out, "local state indicating the red LED light, remote operation of" open and close, stop button does not work, only in the local panel on the operation of "open and close, stop" button.
In the process of opening the valve, the red light flashes and the green light is bright.
In the process of closing the valve, the green light flashes and the red light is bright.
The valve is in the "full open" position, the red light and the green light go out.
The valve is in the "off" position, the green light, red light.
After the "local" operation, the "far" button should be switched to the "remote" operation state. The adjustment of the electric device can be referred to "DZW type valve electric device instruction manual", and the electrical wiring is shown in the WK wiring diagram.
