DeZURIK Double Block & Bleed Knife Gate Valves

DeZURIK Double Block & Bleed Knife Gate Valves provide reliable dual isolation for high-pressure and highly abrasive applications. Combining two knife gate valves with a single actuator and central bleed port, KSV-DBB valves allow downstream isolation and media drainage while maintaining upstream pressure. Ideal for mining, petrochemical and demanding slurry applications.

Description

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.
