Operation Principle
- Uses compressed air to drive butterfly valve operation without a return spring
- Controls rotation of the butterfly valve's disc to regulate media flow
- Operates through two separate air chambers for bidirectional movement
Working Mechanism
- Compressed air supplied to one chamber pushes piston/diaphragm connected to valve stem
- Creates rotational force to turn butterfly disc for opening/closing
- Air redirection to opposite chamber reverses movement
- Provides consistent torque output throughout valve's entire stroke
Applications
- Water treatment systems
- Chemical processing plants
- Oil and gas industry
- Power generation facilities
- Handling liquids, gases, and slurries
Key Advantages
- Fast response time for quick valve adjustments
- Compact design for easy installation
- Simplified maintenance for long-term performance
- Enhanced reliability with no return spring to fail
- Robust construction with corrosion-resistant materials
