DBB Orifice Fitting

The FLOWMASTER Double Block and Bleed Orifice Fitting is a proven system for safely and quickly inspecting and changing orifice plates without breaking apart or depressurizing the flow line.

With an extra intermediate chamber added to the Dual Chamber Orifice Fitting, the DBB Orifice Fitting offers maximum operational safety in highly pressurized processes, allowing orifice plates to be inspected without interrupting the flow.

Benefits:
• Double isolation.
• Easy pressure identification through pressure gauges.
• Safe replacement of orifice plates.
• Reduced operating costs - uninterrupted gas flow while plates are safely inspected.
• Flexibility - Maintenance can be carried out at any time.
