ARO Fluid Power A212PS Air Pilot Valve

ARO Fluid Power A212PS Air Pilot Valve is a four-way, two-position Alpha Series valve that is body-ported and piloted by an external air signal (remote pilot) rather than an electric coil. It provides five ports (P, two work ports, and two exhausts) with 1/4 in NPT connections and is rated for up to 150 psi with a flow capacity of about 30 CFM and 1.5 CV. This spring-return, pilot-actuated valve uses a zinc body and measures roughly 2-15/16 in long, 1-15/16 in wide, and 1-15/16 in high, making it suitable for compact installations. The unit is designed for use with external pilot supplies and can control compressed air, inert gas, or vacuum circuits; no coil is required for operation. Typical applications include control of double-acting cylinders and other pneumatic loads in automation, equipment maintenance, and industrial processes, where remote piloting and reliable, compact packaging are advantageous.
