Vent silencers are used in conjunction with systems that utilize a pressure relief valve (PRV). Typical applications for vent silencers are in oil & gas, industrial and chemical processing, heat recovery systems and steam boilers. B&W Universal’s vent silencers are used around the world in many applications. We have particular expertise as a supplier of steam vent silencers for industrial applications and blowdown silencers for gas compression stations.
HV Series vent silencers effectively silence high-velocity air, steam and gas vents, and blowdowns to atmospheres in which sonic or critical conditions exist in the valve. Typical applications include steam boiler relief valves, superheater header relief valves, boiler startup and purge high-pressure air vents, natural gas blowdowns, switch valves, compressor blowoffs, autoclaves and steam ejectors.
