VALVE SILENCERS
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 plants.d.
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.
