MAC Valves 821C-PM-111CA-152 Solenoid Valve

The MAC Valves 821C-PM-111CA-152 is a high-performance 4-way, 2-position solenoid-operated pneumatic valve designed for industrial automation and control applications. Part of MAC's 800 Series, this valve features a balanced poppet design that ensures consistent shifting forces regardless of pressure fluctuations, providing reliable operation in demanding environments. It supports a pressure range of 10 to 150 PSI and is equipped with 1/4" NPT ports for easy integration into pneumatic systems. Key benefits include fast response times (as low as 10 ms), high flow rates (Cv up to 1.0), and low power consumption, making it ideal for applications in manufacturing, packaging, and material handling where precise control of actuators like cylinders is required. Compared to similar products from competitors like SMC or Festo, the MAC 821C offers superior cycle life (up to 100 million cycles) and better resistance to contamination due to its patented design. Drawbacks may include a higher initial cost and the need for clean, dry air to maintain longevity. This unit appears to be in used but good condition based on visual analysis, with no visible damage, intact wiring, and clear labeling. It includes dual solenoid coils for versatile control and manual override options. For detailed model decoding, refer to MAC's catalog; '821C' indicates the series and configuration, 'PM' for permanent manual override, '111CA' for 120V AC solenoid with conduit, and '152' for specific modifications like lead wire length.
