Ball – N2X

Cryogenic

The Valbart Cryogenic Ball Valve meets demanding end-user requirements for leak rate and fugitive emission performance. It's body construction and flexible trim configurations ensure proper safe isolation. It is bi-directional (std) or uni-directional (upon request), side entry or top entry with fire-safe design, with an anti-static feature and automatic cavity relief.

Cryogenic Side-Entry

Double Block and Bleed

Double Block and Bleed Valve is a side-entry ball valve, with either a bolted or welded body, designed for use in upstream, midstream and downstream oil and gas applications. It requires two in-line isolation valves and a bleed valve used to drain or vent trapped fluid between the two closure elements in order to safely isolate the downstream pipe. This feature can be achieved with one single valves complete with a bleed port between the obturators.
