The Versa ASG-4242-XX-A120 Solenoid Valve (Part No. 3-307-129) is a 4-way, 2-position pneumatic directional control valve that routes compressed air in industrial automation and process-control systems. Solenoid-operated with a spring return and a 120 VAC, 60 Hz coil (A120), it provides reliable switching for pneumatic cylinders, actuators, and other air-operated devices. Its inline-mounted, side-ported body uses threaded ports and is suitable for operation with compressed air or inert gases. The XX hazardous-location configuration denotes a hazardous-location solenoid suitable for explosion-proof or hazardous-duty electrical environments. Common applications include control of double-acting cylinders in manufacturing equipment, packaging machinery, conveyor systems, material handling, and OEM automation panels; it is an OEM replacement part, and common replacements include Versa ASG-4242-W-XX-A120, Versa VSG-4522, and Versa VSG-4222.
