Product Details

DESCRIPTION:

As a kind of check valve, the opening and closing parts of the BS1868 horizontal installation reduced bore flanged end stainless steel spring lift check valve are opened or closed by the medium flow and strength to prevent the medium from flowing backwards. It is an automatic valve type, mainly used for pipes with one-way flow of medium, only allowing the medium to flow in one direction to prevent accidents. It mainly includes these five types: 6 inch check valve, BS1868 check valve, horizontal installation check valve, reduced bore check valve, spring check valve.
