A wafer-type swing check valve having a body flange with a counter-bore into which an easily removable lapped disc support is located. The disc is hinged to the disc support and positioned to seat in a counterbored opening in the disc support to prevent reverse flow. The disc and its support are readily removable as a unit from the valve body. A removable seat may be provided in the disc support to simplify seat relapping.
