Compact Double Block & Bleed vs. Conventional Installations

Double block and bleed valve systems are conventional installations for most End-Users in the Oil and Gas industry. Conventional installations of DBB valve systems have become a normal practice and can even be found on offshore platforms.

The installation of DBB valve systems is a time consuming process that can negatively impact employees and their work production.  The normal process of this type is baded on:

Using two 6” 1500 class ball valve with all the additional materials,
Long and comlex installation process (up to a 41 steps)
Huge amount of material (weight of 2,645 lb(s) = 1200 kg
