FPD190 – Restriction-type Orifice Plates for pressure drop or flow restriction

The FPD190  restriction orifice plates are used where there is a requirement either to reduce the line pressure or alternatively to restrict the flowrate to a certain value.


The FPD190 restriction plate has an orifice bore (and plate thickness) that is calculated to achieve the required restriction to the flow rate or pressure drop whilst maintaining plate integrity. A multi-restriction assembly, consisting of several plates in series, can be engineered for use where the required pressure drop cannot be achieved (or where the noise level would be too high) across a single plate.
FPD190 restriction plates and assemblies are available in a wide range of materials to suit the process conditions.
