Industrial CTD1212 In Tank Check Valve 1/2 In MPT

Industrial CTD1212 In-Tank Check Valve, 1/2 in MPT, is a brass-bodied backflow-prevention valve designed for use in air compressor tanks. It features a 1/2" compression inlet and a 1/2" NPT (MPT) outlet, with tube inlet 1/2" and 1/2" NPT outlet geometry and overall dimensions of C 1.67 in, D 1.95 in, E 2.66 in, and F 7/8 in. The model carries a rated flow of 20 SCFM at 100 psig and a Cv of 2.3, enabling reliable forward flow while preventing reverse flow in typical shop-air systems. This CTD1212 designation corresponds to a 1/2" inlet and 1/2" NPT outlet configuration, aligning with standard 1/2" piping on both sides. Cataloged as an in-tank valve within Sanborn/ Coleman tooling lines, it is intended for integration with tank-mounted setups and is suitable for portable or stationary compressors where backflow protection is essential for downstream components such as regulators and filters.
