Industrial A212SS-O24-A Solenoid Air Control Valve

The ARO Alpha Series A212SS-024-A solenoid air control valve is a four-way, two-position inline pneumatic valve featuring a 24 V AC coil (included) and a base-mounted zinc body for compact installation. It uses internal pilot operation with a spring-return, normally open action, making it a fail-safe choice for automated lines. Ports are 1/4 in NPT for both inlet and exhaust, with pilot ports also NPT and sized at 10-32, and the media supported is compressed air or inert gas. Key performance specs include a maximum operating pressure of 150 psi, a flow coefficient (Cv) of 1.5 and up to 61 cfm, a response time of 22 ms, and a lubrication-free aluminum spool, all intended for reliable cycling in demanding environments. Electrical connectivity is via a DIN solenoid connector, and the unit is cURus listed for quality and safety. The valve measures about 3.25 in high, 1.937 in wide, and 3.437 in long, with a 24 V coil designed for immediate use with no additional lubrication required. This makes the A212SS-024-A well suited for controlling actuators and cylinders in industrial automation, offering precise, fast switching in compact form while remaining compatible with standard 1/4 in pipe fittings and common pneumatic circuits.
