Parker Double Block and Bleed Monoflange Manifolds

Parker now offers a full range of double block and bleed flanged products with fugitive emission options. These products meet Class ‘A’ or Class ‘B’ levels of the ISO 15848 standard for fugitive emissions. They also meet ANSI/ASME B16-34, B1.20.1, and B16.5 codes, as well as BS6755 PART 2/API 607 for fire safety.

The Monoflange manifold range is designed to replace conventional, multiple-valve installations that currently interface with pressure measuring systems. By combining primary and secondary valves into one compact manifold, the number of leak paths is significantly reduced and the system mass is lowered, offsetting the stresses from loading and vibration. This not only improves installation and operational safety factors, it lowers installation cost.
