DB SERIES

The “double block and bleed” guillotine valve was developed especially for applications that use dangerous media. The DB model is a single valve with two seating areas. In the closed position, they provide a seal against pressure from both ends of the valve, and there are bleed holes to flush the cavity between the seat areas. The DB model makes complex and expensive multi-valve systems redundant. Despite these cost benefits, it offers zero leakage protection in difficult applications.
