ROSS Controls 2751A5001 Poppet Valve

ROSS Controls 2751A5001 is a two-way, two-position inline poppet valve from the Classic 27 Series, designed for directional control of compressed air in pneumatic circuits. It has a 3/4-inch NPT port size and standard threaded ports (a BSPP variant is available under prefix D, such as D2751A5001). The 2751A5001 is the normally closed (NC) version, with a counterpart 2752A5001 in normally open configuration. The inline body supports mounting in-line with tubing to control air to actuators, cylinders, and other pneumatic devices, making it suitable for automation and manufacturing lines. The valve employs a poppet design typical of the 27 Series inline valves and, for the 3/4-inch port variant, offers a Cv around 0.34 and an approximate weight of 2.0 lb (0.9 kg). This valve is part of a family that covers multiple port sizes and configurations within the 27 Series, including standard-temperature variants intended for general industrial use. In practice, engineers choose the 2751A5001 when a compact, inline valve is required to reliably switch a pneumatic line on or off in a tight footprint, with easy integration alongside other 27 Series poppet valves.
