The ABO AC083D+922B Pneumatic Butterfly Valve features a snap-in seat design, a spherical sealing surface disc, and a pinless connection between the high-strength disc and shaft. It is widely and reliably used in various industrial fields, especially as a specialized solution in mining, bulk dry powder conveying, paper mills, as well as slurry and high-wear applications.The field-replaceable seat completely isolates the valve body and shaft from the medium, and its heavy-duty structure can withstand pressures from vacuum to 285 psi, making this series a superior choice in food and beverage processing, vacuum desulfurization, marine, HVAC, seawater desalination, air separation, water treatment, and other fields.
