MegaStream control valve trim reduces control valve noise and vibration in a wide range of gas applications. MegaStream works to reduce noise by up to 30 dBa through staging, frequency shifting, attenuation and velocity control. With decades of proven experience, the MegaStream control valve is the one of the most common solutions to control valve noise.

Features & Benefits
- Noise attenuation of up to 30 dBa
- MegaStream uses nested cylinders in place of the seat retainer, each drilled cylinder represents a stage of pressure reduction
- Pressure drops are distributed between the throttling point of the plug and seat ring as well as the stages of the retainer
- Cutting the MegaStream retainer hole size in half will reduce the noise level by up to 7 dBa through frequency shifting effects
- Each stage is designed to take a small pressure drop, avoiding the high velocities present in single-throttling-point trims
- Fluid expansion and velocity are controlled by increasing the flow areas of each subsequent stage
