The Q671F pneumatic actuated butterfly valve is a product in the pneumatic ball valve series, also known as a pneumatic ultra-thin ball valve. It is a new generation of pneumatic short flanged ball valve developed through the domestication of Italian technology by our company, featuring rectangular, V-shaped, and O-shaped core passage shapes. The pneumatic actuated butterfly valve boasts compact structure, small size, light weight, and easy installation. The pneumatic actuated butterfly valve is a new type of ultra-short flanged distance ball valve developed by absorbing Italian technology and undergoing domestic design. The pneumatic actuated butterfly valve and pneumatic ultra-thin ball valve utilize a direct-connection method for actuator connection, offering advantages such as compact structure, small size, light weight, low friction resistance, small hysteresis, and stable and reliable operation. The pneumatic actuated butterfly valve can be widely used in the oil, chemical, metallurgical, power plant, light industry, and other fields for automatic regulation or cut-off control of oil, water, gas, and pulp or fibrous fluids.
