Industrial Multi Turn Rotation Electric Control Valve Actuator 120 Volt Customized

DINKONDA GLOBAL Power Plants Special M Series Built-in Intelligent Controller, Multi Turn Electric Actuator, Multi Turn Rotation, Multi Turn Opening And Closing

Product Overview
The M series multi turn electric actuator is a multi turn intelligent electric drive device that outputs multi turn rotation actions and is suitable for valves such as gate valves, globe valves, and plunger valves that require multi turn opening and closing. The equipment integrates a drive motor, a precision reduction transmission assembly, an intelligent servo controller, a valve position acquisition unit, a local operation panel, and a manual emergency mechanism. It receives DC4-20mA analog adjustment signals or switch signals from the DCS system, drives the valve stem to rotate multiple times, and completes the opening and closing or continuous adjustment of the valve. It is widely used in industrial self-control pipeline systems such as thermal power, petrochemicals, metallurgy, and municipal water supply and drainage.

Structural Composition
1. Intelligent on-site control display unit
Integrated LCD display screen and functional operation buttons, allowing real-time viewing of valve position, operating status, and fault codes on site; Support local/remote control mode switching, complete travel calibration and parameter configuration on site, and facilitate debugging and maintenance. The panel is equipped with LOC/REM on-site remote switch, STOP shutdown button, and mode adjustment button.

2. Drive motor and reduction transmission assembly
The dedicated industrial drive motor is paired with a multi-stage precision gear reduction mechanism to convert high-speed rotation of the motor into high torque, low-speed multi turn output, with strong load-bearing capacity and stable and reliable transmission.

3. Manual emergency operation mechanism
Equipped with an external hand operated handle, it can manually rotate and drive the valve to open and close in emergency situations such as power outages and control system failures, for on-site maintenance and emergency operations.

4. Valve position sensing feedback component
The high-precision angular displacement sensor real-time collects the number of valve stem rotations and positions, outputs DC4-20mA standard valve position feedback signals, and transmits them back to the control system to form a closed-loop control loop, ensuring positioning control accuracy.

5. Multiple security protection modules
Built in torque protection, travel limit protection, and motor overheating protection. Automatic shutdown protection when the output torque exceeds the set threshold; The valve automatically cuts off the motor power when it reaches the fully open and fully closed positions, protecting the actuator and valve body from damage.

6. Explosion proof shell and independent wiring chamber
High strength die cast aluminum alloy shell with anti-corrosion spray coating; Independent explosion-proof wiring chamber, explosion-proof version can be used for flammable and explosive hazardous conditions, equipped with cable sealing joints, and wiring safety regulations.

7. Output connection flange
Standardized multi turn output flange, capable of directly connecting gate and globe valve stems, compatible with mainstream domestic valve connection standards.

Core Features
1. Multi turn torque output
Multi turn rotation output, diverse torque specifications, suitable for multi turn opening and closing valves such as gate valves and globe valves, meeting the driving requirements of large-diameter pipeline valves.

2. Intelligent closed-loop regulation
Built in servo control unit, high positioning accuracy, customizable dead zone control, smooth operation, can be used as a switch type to achieve full opening and closing of valves, or as an adjustable type to achieve continuous control of media.

3. Local/remote dual operation mode
Remote reception of control signals from the control room; The on-site panel can be opened, closed, and stopped locally, and is equipped with a hand cranked mechanism for flexible maintenance and debugging.

4. Fault self diagnosis and alarm
Real time monitoring of motor overheating, torque overload, travel limit, control signal disconnection and other faults, with the LCD screen directly displaying fault codes for quick troubleshooting.

5. Excellent protective performance
Standard protection level IP65, dustproof and waterproof, can operate stably in outdoor, humid, dusty and other industrial sites; Explosion proof model Exd Ⅱ BT4, suitable for chemical explosion-proof areas.

6. Stable operation and long lifespan
Precision gear transmission structure, low vibration, low operating noise, strong overall impact resistance, suitable for long-term uninterrupted industrial operation.
