Allen-Bradley 203A-71 Pneumatic Valve

Allen-Bradley 203A-71 is an automatic pneumatic valve with a 1-inch port size (catalog number 288208). This single-valve unit is designed for pneumatic control in automation systems where simple on/off air flow is required to operate cylinders or pilot-operated devices. As part of Allen-Bradley’s legacy valve lineup, the 203A-71 is built to withstand typical industrial environments and is intended for integration into broader pneumatic circuits rather than as a standalone cabinet component. The 1-inch port size supports standard piping and tubing connections, making it suitable for medium-flow applications in general manufacturing and packaging equipment. The designation “Automatic Valve 203A-71” distinguishes it as a compact, standalone valve designed to be actuated by a pneumatic signal within a control sequence, enabling reliable actuation of downstream actuators without complex wiring. For buyers, the key considerations are compatibility with 1" pneumatic fittings, the single-valve configuration, and its place within legacy Allen-Bradley valve families for retrofit or replacement tasks.
