Ross Controls 2776B4001 Solenoid Directional Valve

Ross Controls 2776B4001 is a four‑way, two‑position inline poppet directional valve from the Classic 27 Series, engineered for standard‑temperature pneumatic systems in automation and manufacturing environments. This solenoid‑pilot controlled valve uses a 1/2" body with 1/2" NPT inlet and outlet ports and 1" NPT exhausts, delivering compact mounting in tight manifolds while maintaining practical exhaust flow. The model 2776B4001 is the 110–120 VAC, 50/60 Hz variant, while the companion 2776B4001W carries a 24 VDC coil; both share the same 4/2 configuration and valve body language. The coil energizes to shift the internal poppets and direct compressed air between ports, with a flow coefficient (Cv) of 5.6, underscoring solid throughput for typical actuator loads. Weighing about 8.1 lb, it provides a substantial, rigid platform for panel or manifold mounting in production lines. Common applications include controlling double‑acting cylinders in automation cells, clamping/fixation stations, and material‑handling conveyors where reliable, rapid actuation and severable air paths are essential. The inline design simplifies plumbing and integration with standard pneumatic components, while the 27 Series lineage promises compatible mounting patterns and serviceable poppets for long lifecycle operation.
