Universal solution for your distinct requirements!

Monoflanges are defined as flanges with integral shut-off valves in a variety of configurations. For shut-off purpose only a single valve assembly is available. The most common assembly however is shut-off valve combined with additional drain / vent valve, or two consecutive shut-off valves in combination with a drain / vent valve in a double block and bleed design. Whereas the Monoflange process side connects directly to the process flange, the instrument connection is either 1/2” NPT female threaded or features a swivel adapter with G1/2“ thread allowing for 360° free orientation of the instrument. Process flanges come in a number of different pressure ranges and sizes; therefore Monoflanges are usually tailor made to meet your specific requirements. tl_files/bollin/img/products/Monoflansche/Monoflansch.jpg
