Will reduce harmful radiant noise generated by the pressure flow rate change inside the valve. They improve the surrounding work environment by lowering ambient sound levels, especially in sensitive locations like mechanical rooms and confined spaces.
Will result in an conservative average sound reduction of 6 dBA overall across the frequency spectrum. A much higher dBA reduction can be expected at higher frequencies. See specifications for details.
Includes both a sound absorption high density, needled fiberglass mat filler as well as a high density barium sulfate vinyl reflector.
