CKDA Series
Advantages and Features of CKDA Series Basic Multi-turn Electric Actuator
1. Pure Mechanical Structure with Ultra-low Failure Rate
This mechanical multi-turn electric actuator adopts a simplified pure mechanical design without built-in intelligent control units and electronic circuit fault points. It is equipped with high-precision worm and worm gear reduction mechanism, achieving a mechanical service life of more than 100,000 full-stroke operations. The overall structure is extremely stable, effectively adapting to harsh industrial environments with high humidity, dust and high temperature.
2. Dual Mechanical Safety Protection Design
As a professional industrial on-off valve actuator, it is standardly equipped with bidirectional mechanical torque limit and stroke limit devices. The independent mechanical switching structure ensures accurate valve position cutoff and overload protection, with a protection response accuracy up to ±2%. It avoids valve and equipment damage caused by jamming and over-travel during long-term on-off operation.
3. Wide Torque Coverage & Strong Compatibility
The CKDA basic actuator supports a complete torque range from 50N·m to 1000N·m, covering most on-off gate valves and globe valves for industrial conventional working conditions. It follows ISO5210 international mounting standards, with universal flange and electrical interface, realizing seamless replacement of old equipment and convenient on-site installation and renovation.
4. High Cost Performance & Zero Daily Maintenance
Eliminating redundant intelligent electronic modules, this dry contact valve actuator greatly reduces procurement and maintenance costs. The reduction box is filled with permanent high-temperature lubricating grease before leaving the factory, realizing zero daily oil replacement and maintenance. It simplifies on-site operation procedures and effectively lowers the long-term operation cost of industrial pipeline systems.
5. Industrial-grade High Protection & Wide Application
This high-reliability valve drive device adopts die-cast aluminum alloy shell with double sealing structure, reaching IP68 high-level protection grade. It stably adapts to conventional island nuclear power, water supply, heating and general chemical industries. It matches external control cabinets to complete centralized on-off control, meeting diverse industrial standard working condition requirements.
The following are common application scenarios for the CKDA Series Basic Multi-turn Electric Actuator：
1. Nuclear Power Conventional Island System
This mechanical multi-turn electric actuator features simple and durable structure with few failure points, fully adapting to the stable operation requirements of nuclear power conventional island auxiliary systems. It is widely used for on-off control of water supply and drainage pipeline valves, providing safe and reliable valve driving for nuclear power supporting facilities.
2. Municipal Water Supply & Drainage Project
Suitable for gate valves and globe valves in water plants, sewage treatment plants and municipal pipe networks, the CKDA basic actuator supports long-term frequent switching operations. With IP66 waterproof and dustproof performance, it stably works in outdoor and underground valve well environments for a long time.
3. Central Heating Pipeline System
Adaptable to industrial and urban heating pipe network valve control, this dry contact valve actuator resists high-temperature and humid working conditions. It cooperates with external control cabinets to realize centralized pipeline switch management, ensuring stable and efficient operation of heating delivery systems.
4. General Chemical Industrial Pipeline
Applied to conventional chemical non-explosive pipeline systems, the industrial on-off valve actuator undertakes cut-off and switching control of process medium pipelines. Its pure mechanical structure avoids electronic component failure caused by chemical dust and corrosive humid air.
5. Industrial General Water & Power Auxiliary System
It is applicable to on-off valves for circulating water, cooling water and auxiliary water systems in power plants and factories. Relying on high-reliability mechanical limit protection, this high-reliability valve drive device effectively prevents pipeline system failures caused by valve misoperation.
