MegaFlo – Noise Attenuation Trim
The MASCOT MegaFlo trim effectively reduces the gaseous noise in control valves. MegaFlo design is a result of extensive research and engineering study. Various principles have been incorporated into the trim design allowing it to be used in varied applications like chemical plants, refineries, power plants, process industries, nuclear industries and wherever a highly effective noise reduction valve is required.

The MegaFlo trim can be applied with 1 to 7 stages effectively reducing the noise by up to 30 dBa.
