Ross Controls 2776B3001Z Pneumatic Solenoid Valve

Ross Controls 2776B3001Z is a Classic 27 Series four-port, four-way 4/2 directional control valve with a single solenoid pilot and spring-return. The solenoid pilot control shifts air between ports, enabling actuation of pneumatic cylinders and other devices in automated lines; in the model-number structure, the 6 in the function code denotes 4/2 operation, and 3001 encodes a 3/8" body/port size. In/out ports are 3/8" NPT and exhaust ports are 1/2" NPT. The coil is rated for 110–120 VAC at 50/60 Hz (suffix Z). The valve body is aluminum, with a Buna-N seal set and a durable acetal/SS poppet. This configuration is widely used for on/off control and sequencing in industrial pneumatic circuits where reliable pilot-operated actuation is required. In the 27 Series model-numbering scheme, a Z suffix indicates 110–120 VAC operation, while a W suffix would denote 24 VDC, allowing selection for different control architectures.
