Noise in some safety and control valves generates levels above 150 dBA / dBC, a situation that is a concern for the technical operations and maintenance of plant. Our silencers reduce the noise generated during atmospheric expansions of steam or gas (vents) during the activation of valves, blow downs and ejectors. Noise exposure increasingly limits system and profitability productivity. Silencers are used to reduce noise in safety valves (PSV), Relief Valves (PRV), starter valves, blow valves, blow downs, ejectors, and discharge tanks.
To design a vent silencer we require the following information:
