Intelligent Electric Valve Actuators Used In Power Plant 2SA8.2 Series 5-40rpm 630C/H 0.37KW 1.3A

DINKONDA GLOBAL Power Plants Special 2SA8.2 Series Intelligent Integrated Type / Multi-turn 630C/h 0.37KW 1.3A 5-40rpm Electric Valve Actuators

Product Overview
2SA8.2 is a large torque intelligent multi turn electric actuator in the DINKONDA GLOBAL 2SA8 series. It upgrades the output torque based on 2SA8.1. It is a dedicated driving device for gate valves, globe valves, and throttle valves in thermal power, petrochemical, water supply and drainage, and thermal power pipelines; The whole machine is equipped with a new generation of intelligent control modules, which support on-site debugging, bus communication, and remote IoT operation and maintenance. It is mainly used for automatic opening and closing and flow regulation of large-diameter valves in pipelines.

Whole Machine Structure Composition
1. Main gearbox: high-strength cast aluminum alloy shell, heat dissipation rib structure, impact resistance and corrosion resistance; Built in high-precision gear reduction components, torque sensors, and absolute position encoders
2. Integrated intelligent control screen: color LCD display screen, function buttons, red mushroom head emergency stop button, on-site view of valve opening, fault codes, and operating parameters
3. Manual operation handwheel: The black three spoke handwheel on the right side is used to manually operate the valve in the power-off state
4. Drive motor compartment, external communication antenna, standard ISO5211 mounting flange base

Core Product Advantages
1. Intelligent remote control
Standard Bluetooth debugging, optional HART, Modbus RTU, Profibus DP industrial bus, wireless IoT module; Support remote parameter modification, fault alarm, operation data storage, program remote upgrade on mobile terminals, upper computers, and cloud platforms, and adapt to smart pipeline networks and unmanned pumping stations.

2. High precision closed-loop control
Position basic error ≤ ± 1%, return error ≤ 1%
Real time torque monitoring, automatic shutdown protection for overload and stuck valves, to avoid valve damage
There are two versions to choose from: switch type and adjustment type. The adjustment model supports 4-20mA analog precise positioning

3. Strict environmental adaptability
Multi layer sealing process for the entire machine, with a standard protection level of IP67; Upgradeable IP68 deep water immersion protection;
The working environment temperature ranges from -30 ℃ to+70 ℃, suitable for outdoor environments, high-temperature boiler rooms, humid sewage treatment plants, and dust chemical plants.

4. Enrich electrical interfaces
Analog signal: DC4-20mA opening feedback, adjustment control signal
Switch contact: Multi channel programmable passive relay, providing feedback on fully open, fully closed, fault, and local remote status
Infrared debugging port, no need to open the cover to read device operation logs

5. Convenient human-machine operation
The LCD screen supports multi language switching, and the main body buttons can complete limit, torque, and communication parameter settings without the need for an external debugger; Capable of one click switching between on-site and remote working modes.
