ROSS Controls 2153A5909 3-Way Pneumatic Air Valve

ROSS Controls 2153A5909 3-Way Pneumatic Air Valve is a compact, spring-return directional control valve designed for reliable actuation in pneumatic circuits. This 3-way, 2-position valve uses 3/4 in NPT-threaded ports and has a 3/4 in body size, delivering a Cv of 7.7 for normally closed operation, enabling controlled flow from supply to a single-acting actuator or to exhaust depending on position. The valve is normally closed (NC), providing a defined path when not energized, and weighs about 1.3 lb (0.6 kg) with a mounting footprint defined by Dimension A of 0.75 in (19 mm). The model number T2153A5909 appears in Ross Controls’ catalog as a 3-way, 2-position spring-return valve, intended for use in industrial automation where compact, pilot-controlled air routing is required. Ports are NPT-threaded, allowing standard pneumatic fittings, and the device is appropriate for pilot circuits, single-acting cylinder control, or interlocking of pneumatic sequences where a reliable, compact valve is essential.
