Ross Controls 411B04 USNT Solenoid

The Ross Controls 411B04 USNT Solenoid is a 125 VDC coil that functions as the single‑solenoid pilot for Ross inline poppet valves in the 27‑series family. This is sold as a complete solenoid assembly intended for use with inline valves and pilots in sizes 8, 12, and 30, providing the electrical actuation needed to control pneumatic flow in industrial circuits. The 411B04 designation is used across Ross catalogs as the standard single‑solenoid pilot coil for these valves, and while 125 VDC is the primary rating for this model, a 24 VDC version of the same coil appears in other Ross listings for alternate control schemes. When selecting, verify compatibility with the valve body and manifold interfaces to ensure correct mounting and electrical connection.
