A monoflange with dual double block and bleed function has been developed for measuring equipment on FPSO vessels.
Designed to offer reduced weight, the manifold, originally developed for a well known energy sector company, provides a way of mounting six valves - and therefore dual double block and bleed function - into one valve body.
The arrangement of valves and design of connecting flow paths was optimized. This provided a monoflange with six integral valves which weighs only only slightly more than a normal standard flange. And, only one valve body is required to lower the risk of leaks.
