Intelligent Manual Emergency Handwheel Electrically Operated Valves Actuator 0~90 ° Angle

DINKONDA GLOBAL Power Plants Special Q Series Explosion-proof Integrated 0~90 ° Angle Travel Manual Emergency Handwheel Electric Actuator

Product Overview
The Q series explosion-proof electric actuator belongs to an integrated angular stroke explosion-proof electric drive device, which outputs an angular displacement of 0-90 °. It is mainly equipped with angular stroke valves such as ball valves, butterfly valves, plug valves, and dampers. The product integrates explosion-proof motors, deceleration transmission components, intelligent control modules, valve position detection units, and manual emergency operation mechanisms. It can receive DC4~20mA analog adjustment signals or switch contact signals to achieve continuous valve adjustment or two position switch control. The product complies with explosion-proof regulations and is suitable for hazardous working conditions with flammable and explosive gases and dust. It is widely used in self-control pipeline systems such as petroleum, chemical, gas, coal chemical, and environmental protection.

Structural Composition
1. Explosion proof intelligent control unit
Integrated explosion-proof control chamber, built-in main control circuit board and valve position acquisition device, equipped with warning signs, operation warning labels, and CE markings on the housing; Support local/remote mode switching, can complete valve stroke calibration and parameter configuration on site, and display valve opening and equipment operation status in real time.

2. Explosion proof drive motor and reduction transmission assembly
Specialized explosion-proof motor, paired with precision worm gear reduction mechanism, converts high-speed rotation of the motor into stable 90 ° angular stroke output. The transmission mechanism has strong load-bearing capacity and stable output torque, which can meet the opening and closing load requirements of various angular stroke valves.

3. Manual emergency operation mechanism
Configure black cast iron handwheel and operating handle, which can manually drive valve opening and closing in case of power failure or control system failure, for on-site maintenance and emergency operation; Equipped with a manual/electric switching lever, the switching is simple and reliable.

4. Valve position sensing feedback component
High precision position sensors collect valve angle in real-time, output standard DC4-20mA valve position feedback signals, and upload them to the central control DCS system to form a closed-loop regulation loop, ensuring valve positioning accuracy.

5. Multiple security protection modules
Integrated torque overload protection, travel limit protection, and motor overheating protection. When the output torque exceeds the set threshold, the actuator automatically shuts down; The valve automatically cuts off the motor power when it reaches the fully open and fully closed positions to prevent overload damage to the valve and actuator.

6. Explosion proof shell structure
High strength aluminum alloy explosion-proof shell, surface anti-corrosion coating, shell joint surface meets explosion-proof and explosion-proof requirements; Independent sealed wiring chamber, cable entry adopts sealed joints, effectively preventing flammable and explosive media from entering the interior of the chamber.

7. Bottom output flange
Standardized angular stroke output flange, can directly connect to ball valve and butterfly valve stem, with strong universality and easy installation.

Core Features
1. Explosion proof safety design
The whole machine is explosion-proof certified and can be used in explosive gas hazardous areas, meeting the requirements of high-risk working conditions such as chemical and gas industries. The explosion-proof shell is impact resistant and has reliable sealing performance.

2. Angular torque output
0~90 ° angular stroke output, with multiple torque specifications to choose from, suitable for butterfly valves and ball valves ranging from light to heavy loads.

3. Integrated intelligent control
Built in servo control unit, high positioning accuracy, and adjustable control dead zone; Simultaneously supporting two working modes: adjustable continuous control and switch type two position control.

4. Local and remote dual operation mode
Remote reception of control room instructions; On site opening, closing, and stopping operations can be carried out on-site, with a manual operating mechanism for easy debugging and maintenance.

5. Fault self diagnosis and alarm
Real time monitoring of motor overheating, torque overload, stroke exceeding limit, signal disconnection and other faults, outputting fault alarm signals for quick troubleshooting by operation and maintenance.

6. Excellent protective performance
The shell protection level is IP67, dustproof and waterproof, and can operate stably in outdoor humid and dusty environments.

7. Compact structure, easy installation
The whole machine has a compact size, light weight, standardized bottom flange interface, simple on-site assembly, and easy maintenance.
