ST-3D™ Noise Plate
Attenuation Diffuser
Categories:
In certain process conditions, the Trimteck ST-3D Diffuser can be used in series with any style valve to reduce the sound level up to 25dBA, while often eliminating the need for more costly in-valve noise attenuation trim.
ST-3D Diffusers share high pressure drops with the control valve, and control the sound level by passing flow at certain conditions through a series of small openings to eliminate excessive turbulence and energy and generate backpressure.
Correct sizing and spacing of the drilled holes is critical, which is why Trimteck custom-engineers each ST-3D Diffuser to accommodate the flow capacity required for any particular application.
- Length and number of drilled holes are custom-designed for specific applications
- Commonly manufactured from carbon and stainless steels, but available in a variety of other materials
