Specification
Double Acting Double Eccentric Pneumatic butterfly Valve for Steam Pipe and Steam Pipe in Valve
In high-cycle applications requiring rapid isolation and precise modulation, traditional valves struggle with wear and response lag. TIANYU’s double-offset pneumatic butterfly valve—crafted from CF8M stainless steel with ISO 5211-compliant actuators—delivers zero-friction sealing, millisecond actuation, and corrosion immunity, setting new standards for chemical processing, power generation, and automated fluid systems.
