MASCOT - Model MegaFlo -Noise Attenuation Trim for Control Valves
The MegaFlo Noise Attenuation Trim by MASCOT Valves is designed to effectively minimize gaseous noise in control valves, making it crucial for industries where sound reduction is imperative, such as chemical plants, refineries, and power plants. Engineered after extensive research, the MegaFlo trim is versatile, being applicable across various stages - from one to seven - to reduce noise levels by up to 30 dBa. The trim incorporates several engineering principles, including controlled velocity during pressure reduction, expanding galleries, and frequency shift technology, to achieve optimal noise reduction. The sound barrier design further enhances its efficiency. Additionally, the MegaFlo trim is designed for easy retrofit into existing GFlo and DeFlo SCV models, eliminating the need for extra components. Its construction utilizes a variety of materials like SS 316, Monel, and Hastelloy, catering to different industrial demands.
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.
- Controlled Velocity during Pressure Reduction: The pressure drop is distributed between the plug and seat and the stages of the retainer avoiding the high velocities caused by single point throttling trims.
- Expanding Galleries: Between each stage the gallery area expands so that as the pressure drops the increased volume is accommodated with the trim allowing for the reduced velocity and noise.
- Frequency Shift Technology: The size of the holes on the retainers are carefully selected and designed so as to ensure that the optimum frequency shifting effect is achieved for noise reduction.
- Sound Barrier Technology: The Multi-Stage MegaFlo is so designed that the outer stage acts as a sound barrier for the inner stage hence assisting with further noise reduction.
- Specially Engineered Solutions: Specially engineered trims are available where process conditions demand additional attenuation that cannot be provided with a standard MegaFlo retainer. MASCOT engineering team has the capability to design and verify the effectiveness of such special trims within an exceptional lead-time.
- Easy to Retrofit: The MegaFlo Trim is retrofittable in the standard GFlo and DeFlo SCV without the need for any special or additional parts.
