Industrial A212PS Pilot Air Valve 2-Position 5-Port

ARO A212PS Pilot Air Valve is a four‑way, two‑position, body‑ported pilot‑operated directional control valve from the Alpha Series. It uses a 5‑port configuration with 1/4 in NPT main ports and a 1/4 in NPT pilot port for external control, and it is rated for a maximum operating pressure of 150 psi. The unit is spring return and has a compact footprint: 2-15/16 inches long, 1-15/16 inches wide, and 1-15/16 inches high, delivering about 1.5 CV (30 CFM) flow. It accommodates temperatures from 0 to 180°F and is designed for use with compressed air, inert gas, or vacuum when driven by an external pilot signal, making it suitable for actuating double‑acting cylinders and other pneumatic devices in automation applications. Model A212PS is part of Ingersoll Rand/ARO’s Alpha Series of pilot‑actuated valves, providing reliable remote pilot control in compact pneumatic circuits.
