DINKONDA GLOBAL Power Plants Special ROTORK CK Series CK60 CK120 CK250 Intelligent Multi Turn Electric Actuator For Single-Stem Penstock Valve

DINKONDA GLOBAL Power Plants Special ROTORK CK Series CK60 CK120 CK250 Intelligent Multi Turn Electric Actuator For Single-Stem Penstock Valve

Product Overview

The ROTORK CK series is a new generation of intelligent multi turn electric actuators, designed specifically for valves such as gate valves, globe valves, and throttle valves that require multi turn opening and closing. CK60, CK120, and CK250 are the mainstream specifications of this series, covering from conventional small and medium torque to high torque working conditions. They integrate motor drive, reduction mechanism, intelligent control unit, and local handwheel operation, with reliable valve opening and closing, stroke control, torque protection, and status feedback functions. They are widely used in industrial self-control pipeline systems such as power, oil and gas, water treatment, chemical, and metallurgical industries, and are suitable for ordinary environments and some explosion-proof optional versions. They are classic actuators for remote automation control of industrial pipelines.

Structural Composition

1. * * Drive motor * *: High insulation level induction motor, sufficient starting torque, short-term working mode, suitable for valve opening and closing intermittent operation conditions;

2. * * Reduction gearbox * *: Precision planetary+helical gear composite reduction structure, smooth transmission, small backlash, stable output torque, and strong load-bearing capacity;

3. * * Manual operating mechanism * *: Equipped with a large diameter black handwheel, it can switch to manual operation without interference in case of electric failure. The clutch mechanism automatically disengages, making manual operation effortless and safe;

4. * * Intelligent control module * *: Built in main control board, travel encoder, torque sensor, supports local/remote control switching, valve position acquisition, and fault self diagnosis;

5. * * Human machine operation panel * *: Integrated valve position display window, local control knob (on/off/off), torque and stroke setting buttons, two adjustment knobs for parameter tuning;

6. Wiring and Sealing Shell: Aluminum alloy high-strength shell, anti-corrosion coating, IP67 protection level, reliable sealing, independent isolation of wiring terminal cavity;

7. * * Output flange * *: Standard multi turn output connection flange, compatible with mainstream gate and globe valve stem interfaces.

Core Features

1. * * Wide coverage of specifications, flexible selection**
CK60, CK120, and CK250 are three models with gradient output torque, which can be matched with DN50~DN600 and above gate valves and globe valves to meet different valve opening and closing load requirements.

2. * * Intelligent adjustment and precise positioning**
Non contact encoder collects valve position signals with high positioning accuracy; Configurable 4-20mA analog valve position feedback signal, supporting remote adjustment and centralized monitoring of DCS system; The stroke and torque are independently adjustable, suitable for different valve sealing characteristics.

3. * * Dual protection mechanism**
**Dual protection of torque protection and travel limit, with the valve automatically cutting off power when in place; When stuck or overloaded, torque protection takes priority action to prevent damage to the mechanical structure of the valve stem, valve body, and actuator; Equipped with motor overheating protection to prevent prolonged stalling and motor burnout.

4. * * Local+Remote Dual Control Mode**
The box panel comes with local on/off/stop operation and also receives remote switch signals; Control logic, valve zero point, and full degree can be directly set on the panel, making debugging convenient without the need for an additional control box.

5. * * High protection, high reliability**
The surface of the shell is coated with anti-corrosion blue coating, with a standard protection level of IP67, and can be installed outdoors; Gear lubrication is a long-lasting grease with a long maintenance cycle; Exd explosion-proof version can be selected as needed for use in flammable and explosive media conditions.

6. * * Comprehensive fault diagnosis and signal feedback**
Equipped with fault alarm: motor overheating, torque overload, travel fault, power failure and other alarm contact outputs. The central control system can capture equipment abnormal status in real time for easy operation and maintenance warning.

7. Hand electric safe switching**
The manual electric clutch adopts an automatic clutch structure, and the handwheel automatically disengages from the transmission chain during electric operation, without rotating with the motor, ensuring the safety of personnel operation.
