Ross Controls 1133A2904 Roller Cam Valve Assembly

The Ross Controls 1133A2904 Roller Cam Valve Assembly is a compact, mechanically actuated valve from the 11 Series designed for inline mounting in automated pneumatic circuits. Cam-roller actuation automatically opens or closes the air path as the machine moves, delivering a robust solution for interlocking and sequencing in manufacturing lines. This family of valves uses 1/4" NPT port connections, and related 11 Series models include the 1133A2001 (3/2 NC, 2-Direction Cam Roller, 1/4" NPT), 1133A2002 (3/2 NC, 1-Direction Cam Roller, 1/4" NPT), and 1133A2003 (3/2 NC, Plunger, 1/4" NPT). Common applications include machine interlocks and automated control circuits, with Ross noting options for safety-rated interlocks—consult Ross for appropriate safety valve products if PLr compliance or SIL requirements apply.
