Campbell Hausfeld CV003205AV In-Tank Check Valve

The Campbell Hausfeld CV003205AV In-Tank Check Valve is a replaceable, one-way valve designed to install inside the air receiver of Campbell Hausfeld compressors, ensuring air flows from the pump into the tank while preventing backflow when the system depressurizes or the unloader valve opens. It uses a 3/4 inch female pipe thread on one end and a 3/4 inch male pipe thread on the other (3/4" FPT x 3/4" MPT), providing a compact, inline connection between the discharge line and the tank in the standard Campbell Hausfeld tank layout. The CV003205AV is documented across Campbell Hausfeld operating manuals and replacement parts catalogs as the in-tank check valve for tanks requiring a 3/4" check valve, underscoring its role in maintaining tank pressure and preventing reverse flow when the compressor stops. Suitable for both stationary and portable Campbell Hausfeld air compressors that specify a 3/4" check valve in the tank assembly, this valve supports consistent discharge pressure during operation by blocking backflow that would otherwise bleed air from the tank back toward the pump.
