Monoflanges and VariAS-Blocks
General Features
Monoflanges
AS-Schneider Monoflanges are designed to replace conventional mutiple-valve installations currently in use for interface with pressure measuring systems. By combining customer specified valves into a single manifold, the number of leak paths is considerably reduced and the mass of the system is lowered reducing the stresses from loading and vibration. The AS-Schneider Monoflange Series are available as Process Monoflanges and Intrument Monoflanges.
Process Monoflanges Process Monoflanges are designed to replace the traditional Primary isolation valve, the primary isolation valve (OS & Y bolted bonnet) incorporates a primary isolate piping valve combined with Instrument double block & bleed functions. |
Instrument Monoflanges Instrument Monoflanges work in conjunction with a pre-installed primary valve to provide a compact instrument block and bleed valve or are used when primary valves with an OS & Y bolted bonnet are not required. |
