Ross Controls 1968D2005 Inline Mounting Check Valve

The Ross Controls 1968D2005 Inline Mounting Check Valve is a 19 Series pneumatic check valve with a 1/4 inch port and BSPP (G) threaded connections, designed for inline installation in compact control lines as part of the low-profile/mid-range D sub-family. It provides Cv 0.5, delivering reliable flow at modest pressures while preventing backflow in pneumatic circuits, making it suitable for actuator control, line protection, leak-prevention in compressed-air lines, and other common automation tasks, optimized for small-diameter lines where space is at a premium. Weighing about 0.5 lb (0.2 kg), this inline valve supports straightforward integration between components, and the 19 Series offers both BSPP and NPT thread variants to match connected piping, with the D-prefix design indicating BSPP threads. Operating pressure is typically 5 to 150 psig (0.3 to 10 bar), aligning with standard industrial pneumatic systems and ensuring predictable check-valve performance across common applications, with inline dimensions that match other 19-Series valves.
