Ross Controls 2751A4001 Pneumatic Directional Control Valve

The Ross Controls 2751A4001 is a Classic 27 Series inline pneumatic directional control valve—2/2 single-pilot, normally closed poppet valve—providing reliable on/off control of compressed air in industrial systems. It is actuated by a pneumatic pilot, mounts inline, and uses 1/2 in. NPT inlet and 1/2 in. NPT outlet ports with a Cv of 7.7. Operating pressure ranges from 15–150 psig (1–10 bar); the fluid media is filtered compressed air, and the valve body is cast aluminum with Buna-N seals, rated for 40°F to 175°F (4°C to 80°C). Designed for continuous-duty industrial pneumatic applications, it is commonly installed in machine automation, packaging machinery, stamping presses, and other pneumatic control circuits that require fast-response, high-flow directional control.
