Tilting Disc Check Valve(Short Type)
A tilting disc check valve wherein a valve module containing the tilting disc is positioned adjacent the inlet of the valve into a valve chamber by a cradle formed by a portion of the interior surface of the wall of the valve chamber and an arcuate ridge formed on such interior surface and spaced a distance from the inlet. A threaded port is formed through the wall of the valve chamber opposite the ridge and a bung, screwed into the port, closes the port and bears against the valve module to seat the module in the cradle provided for the module.
