Double Block & Bleed Valves

Double Block and Bleed Valve can perform the functions of 3 separate Valves i.e. 2 separate isolations and 1 drain Valve, thereby saving space, weight and installation time and maintenance work.

This valve is operating on the principle that the isolation can be done from both side i.e. upstream and downstream.

Different configurations of designs are available such as two ball, gate, globe, needle, etc. Valves are located in a series configuration with the third valve used as bleed valve in the centre cavity.

This valve is used for flow diverting, sampling, injection, maintenance and integrity check of seat leakage through the bleed valve. They are available in different designs i.e.. Single piece design and 3 piece design.
