High Performance Pneumatic Actuated Butterfly Valve for Fluid Control
The buttrfly valves are powered by pneumatic quarter-turn (90°) actuators, available in both double-acting (for consistent bi-directional power) and single-acting (spring-return for fail-safe operation) configurations. Our pneumatic butterfly valves represent the pinnacle of reliability and efficiency in industrial flow control systems. Engineered for durability and precise operation, these valves are the optimal solution for automated on/off and modulating control in a wide range of applications, including water treatment, chemical processing, HVAC, power generation, and general industrial services.
