DeZURIK Double Block & Bleed Knife Gate Valves (KSV-DBB)
DeZURIK Double Block & Bleed Knife Gate Valves are used to isolate and drain downstream system media while safely maintaining upstream pressure. The Double Block & Bleed Knife Gate Valve is ideal for extremely abrasive media in the mining, petrochemical and other industries.
DeZURIK Double Block & Bleed Knife Gate Valves are based on the successful KSV Severe Service Knife Gate Valve design. The Double Block & Bleed design combines two ASME Class 150 or 300 pressure rated knife gate valves into a single unit with a single actuator and a central bleed port. This compact design provides a dual isolation solution. The integral double valve/single actuator design minimizes leak paths, reduces weight and saves costs.
