Compact Double Block & Bleed vs. Conventional Installations

Facts about the Conventional Installation

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)
DBB - At a conventional assembly you have a complex installation and maintenance.

Pros of the Compact Double Block & Bleed Valve solution

In comparison, a prefered method is to use a Compact DBB Valve and not doing a conventional installation with individual valves.

Instead of using two valves in the earlier example, Compact Double Block & Bleed Valves only requires one single valve. This results in:

  • Reduced weight (down to 2,094 lb(s) = 950 kg) –> If the end-user has 10 different DBB valve installations, using Compact DBB Valves would eliminate over 20,000 extra pounds of weight
  • Increasing profits because of minimized shut down time
  • Highest safety with maximizing customer profits
