Home / Liquid application


For liquid applications, The DBB-SAVER will be connected to a Liquid Removal Skid, and this Liquid Removal Skid is connected to the drain connection of the Double Block & Bleed or Single Valve configuration.

The Liquid Removal Skid is sized dependent on the customers max. leak rate specification i.c.w. maximum uninterupted operation time. The Liquid removal Skid is communicating with the PLC of the DBB-SAVER. A layout with “unlimited” operation time is also possible, but requires occasional switching over between liquid catcher vessels, which in turn can be drained.

The ability to apply the DBB-SAVER in a liquid application is in theory dependent on the positions and layout of the valves and interconnecting piping, but in most cases (e.g. horizontal layout) is easily feasible.

Liquid Removal Skid

In case the DBB-SAVER is used on a system containing liquids a Liquid Removal Skid will be connected between the DBB-SAVER and the drain point (between two block valves or the body cavity drain of a single valve).

The liquids can be hazardous, e.g. explosive, toxic, harmful to the environment, etc. The DBB-SAVER in combination with the Liquid Removal Skid will make sure safe work can be performed behind a leaking valve whilst making sure no liquid is spilled into the environment.
