Pneumatic Soft Seal Butterfly Valve series features a disc that rotates within the valve body, controlled by a pneumatic actuator for rapid opening and closing. The soft sealing mechanism, typically made from materials like EPDM or NBR, ensures tight shutoff to prevent leaks. These valves are commonly used in water treatment, chemical processing, and HVAC systems, where reliable sealing and ease of operation are essential.
