The Danfoss 180H4004 is the genuine seal kit for the VCM 22 non-return (check) valve used on Danfoss high-pressure axial-piston pumps. It contains the replaceable soft-seal parts — O-rings and the seat seal — needed to service a VCM 22 valve and restore a leak-free seal, without replacing the complete valve assembly.
Please note: the product photograph shows the assembled VCM 22 valve for identification — this listing is for the seal / service kit only (the soft-seal replacement parts), not the complete valve. For a complete VCM 22 non-return valve, please contact us.

The VCM 22 non-return valve prevents reverse flow at the high-pressure outlet of the pump. Replacing the seal kit at service intervals keeps the valve sealing correctly and protects the pump — more economical than replacing the whole valve.
