Big Bear Instruments offers Block & Bleed Needle Valves in both hard seat and soft seat options. The block valve isolates the downstream process fluids, and the bleed valve exhausts upstream fluids, enabling instruments to be removed without disturbing the permanent piping installation. Sort by manufacturer, series, connection, body material, or item type to find the best valve for your application.
