ABZ A-20 20 30:1 10" 200PSI Butterfly Valve Wafer Disc Manual Gear Operator

ABZ A-20 30:1 10" wafer-type butterfly valve with a manual gear operator is a 10-inch nominal valve rated for up to 200 psi, designed to install between standard flange connections. It features a wafer-style body that sits between two flanges and a butterfly disc that governs flow by rotating to align with or block the flow path. The valve is driven by a 30:1 worm-gear operator, which translates a relatively small manual input into full-range disc rotation, enabling precise positioning through its travel to fully open or fully closed. This manual gear option is intended for situations where electric or pneumatic actuators are unavailable or undesired, offering straightforward maintenance and reliable isolation in mid-pressure piping systems. The 10-inch size and wafer configuration support compact installations in space-constrained pipelines, while the 200 psi rating indicates suitability for moderate-pressure service across various process or utility lines.
