A wafer-type valve for securing between two flange fittings comprises a valve body having a flowway therethrough, connection formations integrally adjoining the valve body and extending radially therefrom, a valve element mounted in the flowway, and adapter means adjoining the valve body and extending outwardly therefrom. First longitudinally extending connectors cooperate between the connection formations of the valve body and the adapters to connect the adapters to the valve body, while second longitudinally extending connectors cooperate between the adapters and the flanges of the flange fittings to connect the adapters to the flange fittings. The valve also includes a seat lining its flowway and a seat retainer axially abutting the seat and one end of the valve body. The adapter overlaps the seat retainer so as to mount it to the valve body.
