Title
(EN) METHOD FOR MANUFACTURING A BLOCK FORGED SWING CHECK VALVE BODY WITH A FULLY ENCAPSULATED SEAT RING
(FR) PROCÉDÉ DE FABRICATION D'UN CORPS DE CLAPET DE NON-RETOUR À BATTANT FORGÉ EN BLOC DOTÉ D'UNE BAGUE DE SIÈGE COMPLÈTEMENT ENCAPSULÉE
Abstract
(EN)
A block forged swing check valve body includes a fully encapsulated seat ring. The swing check valve body includes a through hole and a chamber having a shelf portion defined by a D-shaped passageway. The shelf portion overlies an annular shoulder that encapsulates the valve seat. Methods for the manufacturing and use thereof are also provided.
