What is a double-acting pneumatic actuator for butterfly valves

2025-09-22
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
