Process Monoflanges

AS-Schneider Process Monoflanges (A frequently used term is also Slimline Monoflange) are designed to replace the traditional primary isolation valve and are close coupled to the process piping flange, for connecting process to instruments. The primary isolation valve needs to be of process design, therefore it's a valve with OS&Y Bolted Bonnet. The secondary isolation valve and the bleed valve are provided with screwed bonnets. The combining of piping and instrument valves into a single unit has benefitted various markets. The Standard Pressure Instrument Connection is 1/2 NPT female, the Standard Process Connections are provided with Flange Connections acc. to ASME B 16.5. AS-Schneider is providing axial, radial or dual outlet types for either Horizontal or Vertical Flange Mounting.

The Monoflanges are available as Block, Block & Bleed or Double Block & Bleed designs.

A diverse range of options and the relevant accessories are available, please see below Mounting Bracket Kits and Accessories.

Connections, materials, valve head unit designs and further options are available, please see below Ordering Information or more detailed under:
