CDB Double Block & Bleed Expanding Plug Valve

Description

 

The Double Block & Bleed (DBB) Expanding Plug Valve was developed as an alternative solution to the traditional system made by two inline valves with the bleed in between.
While blocking simultaneously the flow upstream and downstream of the valve, the DBB Expanding Plug Valve allows also to check the tightness of the same, through a bleed system (manual or automatic). DBB Expanding Plug Valves have a rising steam design and a rotating plug with sliding slips that guarantee low torques, friction free strokes and tight shut-off.

Typical applications:
Multi Products Manifold – Metering Station – Loading/unloading Station – Fuel Tanks Storage – Hydrant Isolation – Aviation Fuel Service

Industries:
Petroleum, Refining, Chemical, Aviation, Tank Farm
