This dual pneumatic actuator hygienic butterfly valve operates by using compressed air to drive its two actuators, which rotate the central disc via a through-shaft. Adjusting the disc’s angle between 0° and 90° enables precise control of material flow and dosing. It opens fully for unobstructed material passage and closes tightly to achieve leak-proof shut-off, ensuring stable and reliable performance in hygienic production scenarios.
