MAC Valves 6511B-311-PM-114DA Solenoid Valve

The MAC Valves 6511B-311-PM-114DA is a high-performance 4-way solenoid valve designed for industrial pneumatic applications. Part of the MAC 6500 series, this valve features a 1/2-inch port size and operates on 110/120 VAC at 50/60 Hz, making it suitable for controlling air flow in automation systems, manufacturing equipment, and process control environments. It offers fast response times, high flow rates (Cv up to 4.3), and reliable shifting with minimal lubrication requirements, providing advantages over competitors like slower-response valves from SMC or Festo. Benefits include balanced spool design for consistent performance, modular plug-in solenoid for easy maintenance, and compatibility with manifold mounting. Drawbacks may include higher initial cost compared to basic valves and the need for clean, dry air to prevent wear. This model excels in high-cycle applications such as packaging, material handling, and automotive assembly lines, where durability and precision are critical. Based on the provided images, the unit appears new in original packaging, with no visible wear or damage. For detailed specs, refer to the MAC Valves 6500 Series datasheet (available at https://www.macvalves.com/wp-content/uploads/2020/07/6500-Series.pdf). Model decoding: 6511B indicates single solenoid, internal pilot; 311 specifies 1/2" NPTF ports; PM-114DA denotes plug-in solenoid with 110/120V AC coil.
