Double Block & Bleed Knife Gate Valves (KSV with DBB Option)

The DeZURIK Double Block & Bleed Knife Gate Valve is based on the successful KSV Severe Service Knife Gate Valve design. 

It combines two ANSI 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, allowing personnel to isolate and drain downstream system media while safely maintaining upstream pressure. 

The integral double valve/single actuator design minimizes leak paths, reduces weight and saves costs. 

The Double Block & Bleed Knife Gate Valve is ideal for extremely abrasive media in the mining, petrochemical and other industries.
