Monoflanges

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.

Block and bleed (BB) or Double block and bleed (DBB) construction. The vent connection could be plugged. ANSI B16.5 DIN or ANSI flange dimensions. Sealing surfaces acc. to DIN 2526; EN 1092-1 or ANSI B16.5
ANTI TAMPER facilities at the shut off valves; also lockable. Connections with G- or NPT threads or connec- tions for gauges are possible. But also cutting ring or twin ferrule fittings.

Ausgangsanschlüsse mit G- oder NPT Gewinde und Manometeranschlüsse
sind möglich. Aber auch Schneid- oder
Klemmringanschlüsse.
Möglich ist ein universeller Aufbau für
den horizontalen und vertikalen Einsatz.
