Restriction Orifice Plates

Orifice Plates Products | Restriction Orifice Plates

The OP Series ceramic restriction orifice plates feature a solid ceramic insert enclosed in durable stainless steel housing. Since ceramic is the only wetted component in the process, ceramic orifice plates are:
ABRASION AND WEAR RESISTANT: 99.5% alumina ceramic is more than 7 times harder than stainless steel, whereas Hexoloy silicon carbide is 16.5 times harder than stainless. This allows the use of these ceramic orifice plate materials in erosive services that would otherwise diminish the useful service life of conventional pressure-reducing devices.

CORROSION RESISTANT: Aalumina and silicon carbide are inert to almost all organic and inorganic chemicals used in manufacturing processes.

UNAFFECTED BY CAVITATION: Ceramic orifice plates may also be used in high differential pressure and high velocity services without suffering the damaging effects of cavitation.

Additionally, they are ideal for reducing the pressure, velocity and cavitation that would otherwise damage more expensive, harder to replace valves and critical flow elements.
