Multi-turn intelligent switch type electric actuator LK3 operation panel power controller

Multi-turn valve electric actuator, abbreviated as DZW type electric actuator, is the driving device used to achieve opening, closing, or regulating control of valves. The Z-type electric actuator is suitable for gate valves, globe valves, diaphragm valves, plunger valves, throttle valves, sluice gates, etc. It can be used for rising stem valves as well as non-rising stem valves. 

Multi-turn electric actuators are classified by protection type: standard type, outdoor type, and explosion-proof type.

 Application: The 2SA30 series (S series) electric actuator is used in open-loop control systems and is suitable for controlling regulating valves. It primarily operates in the "open" and "close" positions but can also be set to intermediate positions as needed. If the LK-3 type power control unit is added to the 2SA30 on-off electric actuator, it becomes an integrated control electric actuator, featuring functions such as local operation and remote operation. It is extremely convenient for on-site debugging and is suitable for operating and remotely controlling various valves in open-loop control systems. The electrical control unit (LK-3) consists of multiple modules, including a membrane keypad panel, multifunctional board, control power supply, plug-in board, and AC contactor. The electrical control unit is connected to the electric actuator via execution plugs and fastening bolts, allowing for easy disassembly and replacement. Alternatively, the LK-3 power control unit can be installed in a central control room for separate control, depending on requirements.
