Schneider Monoflange Series

Typical and New System

The Schneider Monoflange Series have been designed to replace the typical system with a compact, weight and cost effective manifold.

The Schneider Monoflange series are available as Process and Instrument Monoflanges.

Features
Weight saving Compact assembly Reduced stress from loading and vibration Reduction of leak points Reduction of installation ad maintenance costs Flanged connections according to ASME B 16.5 Flanged connections according to DIN on request Wide range of instrument and process connections available Full test and material certification according to EN 10 204
Process Monoflange PM Series
The Process Monoflange has been designed to reaplace the root valve-manifold assembly. This is the most cost-effective solution. Available as: Block, Block & Bleed or Double Block & Bleed Design
Instrument Monoflange IM Series
The Instrument Monoflanges are used when root valves are not required or when the root valves are not to be replaced by a Process Monoflange (in this case the IM-Monoflanges can be directly flanged to the root valve). The IM Series are available with two outlets (for horizontal or vertical mounting) or alternatively with one outlet, then however two monoflanges per size are requested, one for horizontal and one for vertical mounting option.
