Precision Small Electric Valve Actuators AC220V AC380V DC24V 0~90 ° Angular Stroke Exd Ⅱ CT4

DINKONDA GLOBAL Power Plants Special VR Series IP67, AC220V/AC380V/DC24V Precision Small 0~90 ° Angular Stroke Exd Ⅱ CT4 Explosion-proof Electric Actuator

Product Overview
The VR series precision small explosion-proof electric actuator, angular stroke explosion-proof electric drive device, belongs to a compact and compact structure, outputting 0-90 ° angular stroke, specially matched with ball valves, butterfly valves, plug valves and other angular stroke valves. The whole machine integrates a drive motor, a reduction mechanism, an intelligent control module, and a valve position feedback component. It is compact in size, easy to install, and has explosion-proof performance. It is suitable for hazardous working conditions with flammable and explosive gas media, realizing remote valve opening and control, and widely used in explosion-proof pipeline self-control systems such as chemical, gas, oil and gas, and pharmaceutical industries.

Structural Composition
1. Intelligent explosion-proof control unit
Built in explosion-proof control motherboard, valve position visual indicator window intuitively displays valve open/close status; Supports local/remote control switching and can complete travel calibration on site. Optional DC4~20mA signal regulation, supports bus communication, and can be connected to DCS and PLC systems. The explosion-proof shell is sealed and isolated, and the control circuit is isolated from the external environment to meet explosion-proof safety requirements.

2. Drive motor and reduction transmission assembly
Adopting a dedicated small explosion-proof motor, it starts quickly and has a compact size; Paired with a precision helical gear reduction mechanism, the motor rotation is converted into a 90 ° angular travel output, ensuring smooth transmission and stable output torque. The motor is equipped with overheat protection, which makes it difficult to burn out due to short-term overload.

3. Valve position indication and position sensing component
The top is equipped with a visual valve position indicator, which can intuitively observe the position of the valve switch; High precision position sensors collect valve position in real-time, output standard DC4~20mA valve position feedback signals, accurately feedback the actual opening of the valve, and achieve closed-loop regulation.

4. Security protection module
Built in bidirectional mechanical travel limit and motor overheating protection. The valve automatically cuts off the motor power when it reaches the fully open or fully closed position; The motor will automatically shut down if the temperature rise exceeds the standard, protecting the actuator and valve to prevent damage to the valve body due to overtravel.

5. Explosion proof shell structure
Die cast aluminum alloy explosion-proof shell, surface anti-corrosion coating, precision machining of explosion-proof joint surface, meeting Exd explosion-proof standards; The overall protection level of the machine is IP67, dustproof and waterproof, suitable for outdoor humid and dusty hazardous environments, independently sealed wiring chambers, and safe wiring.

Core Features
1. Compact and compact structure
The whole machine has a small volume, light weight, and low installation space requirements. It can be directly installed on small butterfly valves and ball valves, and is easy to disassemble and assemble.

2. Explosion proof and explosion-proof design
Exd explosion-proof structure, suitable for Class II explosive gas environment, meets the requirements for use in chemical and gas hazardous areas.

3. 0~90 ° angular travel output
Standard 90 ° rotation, compatible with various types of angular stroke valves, supporting two control modes: switch type and adjustment type.

4. Local+remote dual control
Support remote signal control in the control room, on-site debugging and operation, and simple inspection and maintenance.

5. Visual valve position display
The top has a valve position observation window, which allows for intuitive judgment of valve opening and closing status without the need to open the cover.

6. Standardized installation interface
The output flange complies with the ISO5211 standard and is compatible with mainstream domestic and foreign brands of ball valves, butterfly valves, and plug valves.
