Description
The flanged pressure reducer assembly is required to
restrict the flow of INERGEN
®
agent thus reducing the
agent pressure down stream of the pressure reducer. The
flanged pressure reducer assembly contains a stainless
steel orifice plate which is drilled to the specific size hole
required based on the flow calculation.* The orifice plate
provides readily visible orifice identification. The flanged
pressure reducer assembly is available in three sizes; 2
1/2, 3, and 4 in. Each size is available in threaded, slip-on,
and weld neck flange.
All orifice plates must be installed in the piping system with
the orifice identification information on the tab facing the
pressure inlet side of the system.
