Allen-Bradley 407D431A9D1A Pneumatic Spool Valve

The Allen-Bradley 407D431A9D1A‑A is a 5/3‑way, air‑pilot, solenoid‑operated pneumatic spool valve in the A04 Series, configured for 1/4 in port connections. This compact valve controls air flow to downstream actuators by moving its internal spool through three positions, enabling directional control of a five‑port circuit for cylinders or actuators in automated equipment. Designed for air‑pilot actuation, it supports compact installations where space is limited while delivering reliable switching performance in industrial control panels and automation cells. As part of the A04 Series, it shares a common platform that facilitates mounting and integration with compatible sub‑bases and manifolds. For installation or retrofit, verify model‑specific details from the supplier or Rockwell Automation catalog to ensure correct electrical and enclosure characteristics for your application.
