Ingersoll Rand A239SS-120-A Industrial Pneumatic Solenoid Valve

The Ingersoll Rand A239SS-120-A is a four-way, three-position solenoid-operated directional valve from the ARO Alpha Series, designed to precisely route compressed air in industrial automation. With 1/4-inch porting, it supports compact valve assemblies for directing air to cylinders or actuators while venting exhaust to atmosphere. The A239SS-120-A is built for reliable performance in demanding environments and uses a 120-volt supply coil rated for 50/60 Hz operation common in factory pneumatic circuits. The unit weighs about 0.60 lb, making it suitable for tight control panels or modular manifolds. Ideal applications include control of double-acting cylinders on automated packaging lines, pick-and-place systems, and general manufacturing equipment where responsive, clean air control is required. This Alpha Series valve is designed for robust, long-term service and integrates with standard pneumatic fittings and manifolds for straightforward replacement in legacy Ingersoll Rand installations. Designed to withstand typical factory temperatures and vibrations while delivering precise actuation in continuous operation.
