Industrial CV310000AV Air Compressor In Tank Check Valve

CV310000AV is an in-tank check valve for air compressors, configured with 1" female pipe thread (FPT) on the inlet and 1" male pipe thread (MPT) on the outlet. It provides one-way air flow from the compressor into the tank while preventing reverse flow, helping maintain stored tank pressure and supporting proper unloading in compatible systems. This 1" x 1" configuration matches standard pipe-thread fittings, enabling straightforward replacement in a wide range of portable and workshop compressors. Campbell Hausfeld literature identifies CV310000AV as a 1" connection in their in-tank check valve assemblies, noting a side-port option for potential unloader connections in certain installations. By design, it integrates with common 1" pipe-thread components, making it a go-to replacement part when servicing in-tank valve assemblies for air compressors that rely on reliable check-valve operation.
