Pneumatic Actuated Flanged Butterfly Valve – High Performance Automation

Engineered for rapid response and precise flow control, this Pneumatic Actuated Flanged Butterfly Valve is the ultimate solution for industrial automation. Featuring a heavy-duty double-flanged body and a high-efficiency pneumatic actuator (available in double-acting or spring-return), it ensures reliable, fail-safe operation in critical piping systems. Ideal for chemical processing, water treatment plants, and power generation facilities.

🏭 Engineering Highlights:

  • Actuation: Rack and pinion pneumatic actuator for fast open/close cycles.
  • Connection: Double flanged design for maximum structural integrity.
  • Performance: Bi-directional zero-leakage shut-off.
  • Accessories: Can be equipped with limit switches, solenoid valves, and positioners.
