Design Details: Double Block and Bleed is a means of establishing positive isolation between two sections of a pipe system. Two independent seals close tightly at upstream and downstream ports (Double Block) and the pressure trapped between them is relieved, either manually or automatically (Bleed). The design ensures tight sealing even in low pressure applications and extends valve life by eliminating seal abrasion.
