DB Series

DB Series The “double block and bleed” knife gate valve was specially developed for applications using hazardous media. The DB model is a single valve with two seat areas. In the closed position, these provide a seal against pressure from both ends of the valve, and there are purge ports to flush the cavity between the seat areas. The DB model thus makes complex and costly multiple valve systems redundant. In spite of these cost benefits, it offers zero leakage protection in difficult applications.
