MAC Valves PME-221JB Pneumatic Solenoid Valve

The MAC Valves PME-221JB Pneumatic Solenoid Valve is a pilot-operated, single-operator valve that precisely directs compressed air in automation equipment and industrial motion control systems, making it well suited for packaging machinery, assembly equipment, material handling systems, robotic work cells, and OEM automation gear where fast switching matters. It operates at 24 VAC, 50/60 Hz, drawing 6.7 W, and uses a rectangular connector, with a non-locking recessed manual override for manual actuation when needed. The valve functions as a pneumatic directional control device and supports mounting on a manifold or as an individual valve (series dependent), enabling flexible integration in compact spaces or modular layouts. Weighing approximately 0.87 lb (0.39 kg), the PME-221JB is designed to endure typical industrial environments and deliver reliable operation in compressed air automation systems. In practice, it is commonly used with pneumatic cylinders, packaging equipment, conveyor systems, pick-and-place machines, textile machinery, and manufacturing equipment where reliable, fast-response control is essential. For maintenance and retrofits, it is commonly chosen by system integrators and maintenance teams, with common replacements including PME-111JB, PME-611JB, and PME-221BA.
