By combining customer-specified valves into a single manifold valve, BEPL’s Mono-Flange significantly reduces the number of potential leak paths. The Mono-Flanges also have a lower system mass, which reduces loading and vibration stresses, further improving safety and reliability. The BEPL Mono-Flange has needle valve primary and secondary rather than ball valves. The Mono-Flange is preferred by some operators as it is smaller than a traditional double block and bleed valve, giving even more space and weight advantages. This ensures that the Mono-Flange is it is a cost efficient option for owner / operators.

The Mono-Flange allows the mounting options to suit whether the pipeline is vertical or horizontal; the gauge or pressure transmitter can be fitted on either the front face or on the outer diameter of the body to allow good orientation and ease of reading.

BEPL’s Mono-Flange is available in a wide range of single-, two- and three-valve configurations, including block, double-block, block-and-bleed, double-block-and-bleed and block-bleed-block. Standard flange sizes include 1/2″, 3/4″, 1”, 1-1/2” and 2”, together with API and DIN standard versions, and there is an extensive choice of flange classes,  from AN S I 1 5 0 to 2 5 0 0 . Standard outlet vents are 1/2″ female NPT.
Depending on Mono-Flange size and configuration, other options include 1/4″, 3/8”, 6 mm, 10 mm and 12 mm sizes, and male NPT or BEPL double ferrule compression fittings.
