Category:

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.
