ARO A222PS is a four-way, two-position, pilot-operated air control valve from the Alpha Series designed to direct compressed air to a double-acting cylinder while exhausting the remaining ports. It features 1/4 in working ports and 1/4 in inlet ports, with a 1/8 in NPT pilot port and a spring return for the unactuated position, shifting on a 50 psi pilot signal. The valve is rated for a maximum operating pressure of 150 psi and delivers up to 68 CFM of flow. Its compact footprint measures roughly 3.25 in long by 1 in wide by 2.44 in high, enabling stacking in Alpha assemblies to form modular pneumatic manifolds for multi-valve control in automation systems.
