Ross Controls 2773B2001 Directional Control Valve

The Ross Controls 2773B2001W is a Classic 27 Series poppet directional control valve that provides 3/2 (three-port, two-position) control for pneumatic circuits and is normally closed. Powered by a 24 VDC solenoid (W suffix), it uses pilot-assisted actuation to shift flow between ports, turning inlet air selectively to the output port while venting the exhaust. The model code 2773B2001W encodes a 1/4" body with 3/8" ports (2001 body/port code) and a revision level B, with the W designation indicating a 24 VDC coil. This 27 Series valve is designed for standard-temperature operation and belongs to Ross Controls' line of compact, poppet-style valves, suitable for space-constrained automation and machine control. In typical applications, it can control a pneumatic actuator in logic circuits, sequencing, clamping, or cycling a single-acting or double-acting cylinder where a compact, reliable 3/2 valve is required. The configuration and port arrangement support inlet, outlet, and exhaust paths arranged for 3/2 operation, and the small form factor makes it a common choice for retrofit or new design in automation panels, tool machines, and packaging lines where precise pneumatic directional control is essential.
