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
