Electric Flange Gate Valve with DZW20 On/Off Electric Actuator

Multi-turn valve electric actuators, abbreviated as DZW type electric actuators, are driving devices used to achieve the opening, closing, or regulating control of valves. Z-type electric actuators are suitable for gate valves, globe valves, diaphragm valves, plunger valves, throttle valves, sluice gates, etc. They 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.

               By control method: conventional type, integrated type, and smart integrated type.

               By connection type: torque type, power station type, and thrust type.

 The integrated switch type is equipped with a remote control module, supporting remote jog or linkage operation, and outputs a 4-20mA current feedback signal. It does not require a matching electric control box/cabinet for centralized control. On-site buttons allow local control, while remote control is achieved through DCS or PLC centralized control, with corresponding 4-20mA feedback signals output. It supports continuous operation via on-site buttons, as well as remote, centralized, and automatic control. It includes phase sequence identification and phase loss protection functions.
