DINKONDA GLOBAL Power Plants Special Rotork CKC Centronik Isolating Duty Domestic Replacement For Intelligent Isolation Multi Turn Electric Actuators

Product Overview

This domestically produced alternative actuator is a modular split intelligent control isolation actuator, which is the benchmark for the Rotork CKC Centronik isolation duty model. Unlike the simple CKA Atronik structure, the core highlight lies in the separable intelligent main control unit architecture. The biggest feature of the original Centronik is that the control module can be integrated into the main body or remotely separated and installed up to 100 meters away, specifically solving harsh on-site conditions such as small valve installation space, high temperature radiation, and high humidity corrosion; The domestically produced model fully replicates this remote control architecture, with flange, valve stem interface, cable pin definition, and upper computer communication protocol compatible with the original CKC. It supports in-situ modification of projects, complete valve matching, and does not require changes to valve brackets and pipeline layout. It is suitable for process isolation valves with high requirements for status diagnosis and data transmission in large power plants, oil and gas stations, and coal chemical plants.
The product is positioned for Class A/B isolation conditions, focusing on low-frequency opening and closing, long-term static isolation, and does not aim for continuous flow regulation. However, it is equipped with fully functional intelligent acquisition, recording, and bus interaction capabilities, making it the high-end intelligent version of Rotork in isolation valves.

Core Architecture

1. * * Split type intelligent control unit**
There are two installation modes for the control motherboard module: coupling it to the actuator housing nearby, or installing it separately on the wall or cabinet. The signal cable supports up to 100m transmission. When the valve body is in a high-temperature flue, valve well, or narrow valve group layer, only the gear transmission body is installed on the valve, and the human-machine interaction display panel is arranged in a safe area for easy inspection and debugging to avoid aging damage to the circuit board caused by high temperature, water vapor, and dust. The module is connected with a quick plug aviation plug, which can be disassembled without rewiring, making maintenance and replacement very convenient.

2. DSM digital position sensing system (power-off position memory)**
Equipped with domestically developed non-contact absolute value encoder DSM digital switch mechanism, it continues to lock and memorize valve position values even after power failure. It automatically reads back historical position and torque records when powered on, without power failure or zero drift. The torque limits for fully open and fully closed are independently set in both directions, and the overload thresholds for open and close directions can be configured separately to adapt to process pipelines with asymmetric pressure differentials (high-pressure differential valve closing conditions) Rotork.

3. Non invasive multi-path parameter tuning**
Retain the on-site knob and infrared setter debugging method, upgrade Bluetooth local debugging; The menu is a native Chinese interface, with password level permission management and parameter modification to keep operation logs throughout the process. Support one click configuration of torque threshold, limit position, alarm threshold, and bus address, greatly reducing the operation of opening and adjusting mechanical limits, and reducing the risk of seal failure.

4. * * Built in event data recording unit**
Equipped with large capacity local storage, it automatically records action time, valve position curve, trigger torque, fault codes, and power outage events. Equipped with domestic PC analysis software, it can export logs for fault tracing and periodic condition evaluation, replacing the original Insight2 data analysis function, and meeting the data retention requirements of power plant SIL ledger, safety evaluation, and regular verification.
