AISI 904L Butterfly Valves

Butterfly Valves

AISI 904L Butterfly Valves are quarter turn valves that can be used for control flow of liquid or gas by means of a disc that is connected to a stem. Common types of AISI 904L butterfly valves includes concentric and eccentric (single offset, double offset and triple offset) designs.
