ST-3P™ Diffuser Plate Noise Abatement Device
Categories:
In certain process conditions, the Trimteck ST-3P Diffuser Plate Noise Abatement Device can be used in series with any style control valve to reduce the sound level up to 25dBA.
ST-3P Diffuser Plates 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 – through various stages – 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-3P Diffuser Plate to accommodate the flow capacity required for any particular application.
-
- Stages minimize turbulence and absorb pressure drop
- Commonly manufactured from carbon and stainless steels, but available in a variety of other materials
