Seal kits & screw set for Check Valves
The Danfoss 180H4000 is the genuine seal kit for the VCM 46 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 46 valve and restore a leak-free seal, without replacing the complete valve assembly.

The VCM 46 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.
