Overview
The Fabco-Air 14PMD-4 is a manually-actuated 4-way (5/2) pneumatic directional control valve from Fabco-Air’s proven 14 series. This compact, door-mount valve features a black phenolic push-button with detented (push-pull) actuation, making it ideal for applications requiring simple, reliable directional switching of compressed air. Built with a black anodized aluminum body and nitrile rubber seals, the 14PMD-4 combines robust construction with proven field performance across industrial automation, machinery control, and pilot-operated systems.
